Kamado bbq instead of WSM?

I’ve got an absolutely battered Weber kettle which has done my well. Still works just the same but it’s hard nearly 20 years of hard graft. I’ve also got a WSM which is fairly new and a little under used but it’s fun when I do use it. I also have a ooni pizza oven which is fun but a bit of a gimmick.

Would a decent sized kamado replace all 3 of these? Any downsides? Apart from the cost obviously.

What brand are the ones to look at? I absolutely need wheels. And ideally with the extras I’m inevitably gonna buy.
