So far for cupsoles, I've skated the Ave Pros, which have a good balance between boardfeel and support. Toward the end of their lifespan they definitely start to feel less supportive, but maybe that just means it's time to retire them and not a fault of the shoe. Are they technically cupsoles? They're a sort of hybrid cup/vulc. I actually really like these for skating in and have skated quite a few pairs now.
Then I skated the Lakai Telford. They were nice in the beginning but the soles felt too thin after a while and skated basically like vulcs once the tread had worn down quite a bit. They were a bit painful in fact at that point, like there wasn't much separating my feet from my board.
After that I bought a pair of NB 1010s (my first corporate skate shoe purchase) because of all the rave reviews on Slap and elsewhere. I've tried skating in them a couple times now, including once today, but I just can't do it. They're too clunky for me. Maybe they skate better after skating in them a lot? However, I don't really have the patience for that. I've already worn them around for over a month but they still feel like moon boots to me when I try tricks. I don't get how people skate in these.
Gonna skate the Joslin 2s next and see how they feel.
The KSL G6s sound like they would work for me too based on this thread.
Edited to add this postscript: I actually bought another colorway (black) and material (suede with mesh) of the 1010s because they were on sale, and for some reason when I walk around in them they feel way more flexible and like they would have decent boardfeel. Maybe the other ones I have, the white suede, are just a stiffer and bulkier material? Even walking around in these black mesh ones feels different, and they look less beefy.
