I only started with BG3 after patch 5 dropped, so I've not got anything prior to compare to. I never played any prior BG titles, and got bored of DoS after 12 hours, so I can't make any comparisons in that department. I only ever heard of BG because I'm such a fan of PoE (both). So that's where I'm coming from here.
I wish there were:
* a control/alt/whatever key +click to send items to camp/wares instead of right-clicking
* a party-wide crouch interaction
* pause during non-combat without going into turn-based so one can issue orders to all the party at one go, then unpause
* when disbursing items from a crate, it would convenient if the modal closed when the last item is removed
* more clarity around concentration - I grew up on 2e and 3e, and I only know 5e from introducing my kids, and the complexity is such that my initial reaction to 5e was "holy crap, this should be a video game, not a pen and paper game!" THAC0 makes perfect sense to me, all the fiddly little 5e rules don't, so yay! make it a video game, but it's totally unclear to me through the UI when a character has concentration or not or what that means in practice
All the other stuff in other threads, movement & pathfinding, etc, that's all bug fixing, whatever. I liked a suggestion someone else made about making non-selected party members essentially ghosts until pathfinding is better. Other plot things... meh. This is strong as it is, especially for an early access act 1. I've happily dropped 10x as many hours into this as I did into the full-release DoS. The story is compelling, the acting is superb, and the mechanics aren't upsettingly troublesome, nothing unreasonable for EA status.
But those points above, those are the little naggy things that are repetitively annoying
