The one that never starts to smell.
Plastic trays smell because claws score the surface and urine soaks into the scratches. Steel does not scratch, so there is nowhere for it to soak into and nothing to develop.

Why you'll love it
Every scoop leaves fine scratches in a plastic tray, and urine soaks into them. That is why an old tray smells within minutes of cleaning. Steel has no pores and does not scratch, so the smell has nowhere to live.
Most litter on the floor is kicked over the side by a cat digging. 30cm walls with a curved lip keep it in, and the mat catches what comes out on their paws.
A cat should be able to turn a full circle and dig without touching the sides. At 60 x 40cm this suits large breeds and multi cat homes, where a standard tray is the reason someone starts going on the carpet.
Good fit if
Look elsewhere if
A cat digs before and after using a tray, and its claws score the plastic every time. Those scratches are microscopic at first and they accumulate over months, and urine works into them. Once it has, washing the surface does not reach it, and the tray smells even when it is objectively clean.
That is the point at which most owners buy a new tray, and the cycle restarts. It also matters to the cat before it matters to you, since a cat's sense of smell is far better than ours. A tray that smells faintly to you may already be one your cat is reluctant to use, and reluctance is how tray avoidance starts.
Stainless steel is hard enough that claws do not mark it and nonporous, so nothing soaks in. The surface you wash is the whole surface, and it stays that way for the life of the tray. Practically, this means one tray rather than a plastic one replaced every year or two, which is most of the cost argument.
The high plastic surround does a different job. Cats that dig enthusiastically spray litter well past the edge of a low tray, and thirty centimetres of wall contains almost all of it. The combination is a tray that neither smells nor distributes its contents across the floor, which are the two complaints people have about litter trays.
At sixty by forty centimetres this is larger than most trays sold, which is a feature. The guidance is roughly one and a half times the cat's body length from nose to tail base, and most commercial trays fall short of that for an average adult cat, let alone a large breed.
Fill it three to four centimetres deep. That is enough to dig properly and shallow enough that the cat is not wading, and it is the depth most cats prefer when given a choice. Deeper is not better: it wastes litter, it makes scooping harder, and plenty of cats actively dislike it.

The details
Scoop daily, without exception. That is the single most important thing, and it matters more than the tray or the litter. Cats are fastidious about where they toilet, and a tray with yesterday's waste in it is one many cats will decline in favour of a rug.
Change the litter completely every two to three weeks with clumping litter, or weekly with litter that does not clump, and wash the tray at the same time. Warm water and unscented washing up liquid is right; the steel tray is dishwasher safe if it fits. Avoid anything strongly perfumed, and never use a product containing ammonia, since ammonia is a component of urine and a cat reads it as another cat having already claimed the spot.
Loved by real pet parents
We went through three plastic trays in four years and each one started smelling within a day of being washed, exactly as the description says about scratches. The steel tray has been in for five months and it rinses back to nothing. It is 2.6kg before any litter goes in though, so carrying a full one to empty it is a two handed job.
The 30cm walls have made the biggest difference. Our boy digs like he is burying treasure and most of it used to end up on the floor beside the tray, whereas now the curved lip throws it back in. The mat catches what he carries out on his paws.
Our girl is a long cat and in her old tray she had to reverse out because she could not turn. The 60 by 40 floor gives her room to circle before she settles, and she started using it the same afternoon. The scoop clips into its wall holder so it is not propped in a corner any more.
No complaints about the steel itself, it wipes clean and there is nothing for a smell to sit in. Getting the plastic surround back onto the tray after washing takes more lining up than I would like and I have pinched a finger doing it twice. It works, I just find that part more of a faff than it should be.
The thing that sold me was the tray being dishwasher safe, so once a fortnight it goes in on a hot cycle and comes out like new. No scrubbing and no bleach smell in the kitchen. Five months in and there is not a single scratch on it.
I was braced for it to look like something from a laboratory, but the light grey surround is soft enough that it sits in the corner of our utility without shouting. The practical side is sorted too, with the mat and the scoop in the box there was nothing else to buy.
Litter on the floor has dropped hugely thanks to the high sides. The trapping mat included does catch a good amount, but ours has started to curl at one corner after a few months of being tipped out, so it no longer lies flat. The tray is the star here and the mat is a decent extra.
Our hallway had a permanent background smell that I had put down to the cat and it turned out to be the tray. We swapped to the steel one and within a week you could not tell there was a litter tray in the house. I am slightly annoyed at how long I put up with it.
Measure before you order, because 60 by 40 is a proper footprint and it only just fitted the gap beside our washing machine. Once in, it is exactly what we wanted and our two use it without any fuss. I would happily have a second if we had the floor for it.
Good questions
It is generous rather than excessive. A cat should turn a full circle without touching the sides, and most trays sold as large do not allow that. If you are short on floor space, measure 60 x 40cm first.
Litter sits several centimetres deep, so the cat never touches the metal. Scooping against steel is slightly louder than plastic, which is the one real compromise.
No. Most trays sold are too small rather than the other way round, and the guidance is roughly one and a half times the cat's body length. A larger tray is used more willingly.
It is not noticeably cold once litter is in it, and litter muffles the sound of digging. Cats generally take to it within a day or two if you move the litter across from the old tray.
One per cat plus one spare, in different rooms. Two cats need three trays, and lining several up in one room counts as a single location as far as the cats are concerned.

Advice
Scoop twice a day, strip the tray weekly or fortnightly depending on litter type. If it smells, the schedule isn't your problem.
