With so much emphasis placed on the roster… people haven’t been discussing the stages much.
Of course for 1v1 no items, Final destination and battlefield seem to be common, but I think there are alot of amazing stages, both competitive and for casual play.
Personal I enjoy most of them. I find the Mushroomy Kingdom stage amazing personally, as long as with its alternate underground variant. Mario Kart stage is also a favorite of me , probably because of fond memories of that game.
Stages I hate playing on are New Pork City and Hyrule Temple… probably because I play Ike alot and huge open stages are not his friend…
The stage builder is also pretty awesome, and playing with the stage of the day from nintendo has been pretty cool, though the two i’ve played have been somewhat plain so far.
I haven’t gotten around to building my own stages yet, but I’m sure some people have made some amazing creations. It’s just unfortunate they can’t be used online.
