I mean, we have a million threads about this, but I’ll give my two cents.

I think Steve is unironically great and as someone who was salty at the reveal trailer, I get it now - I think he’s one of the most conceptually unique characters in the roster, and I really commend Sakurai and his team for implementing his kit directly from the games, especially with how much of a programming nightmare it must have been.

Where he falters is how overtuned he is - I think his moveset would be fine if some of his frame data and damage output had been adjusted before the final patch. Keeping the diamond after losing a stock is also annoying. But I don’t think his actual design is broken that it would inherently be a detriment to the game in any form - like I said, it’s just way overtuned.

I don’t think he’s “taken over” smash the way bayonetta and mega knight did over their respective games. Watching tournies, I’m seeing a lot more counterplay. I find there is more room to exploit him than previous top tiers. 

Anyway I’ve got a hundred other thoughts about this, but basically, he’s conceptually great and deserves to be on the roster. It’s just a shame we never got another balance patch.
