I much prefer a hub based design with numerous maps and points of interest, so like in the original BG series or original Fallout series.
I also like large maps, so make them large, when it makes sense.
Also, I didn't really enjoy D:OS 2 style corridor maps too much.
All that said, BG3 is a D:OS 2 clone, so Larian is probably going to copy their map design 1:1 for this game.
