I wanted to try something new and I had not yet played Pathfinder, so I picked up Kingmaker with all it's DLC while on sale and gave it a shot. I began with Normal mode but did limited saves and started out. HOLY CRAP, this game made me think and work way more in actual tactical combat than BG3, that is for sure. Further this is not the hardest mode.
I have been defending BG3's difficulty but now I have to say, okay I see it.
I'm currently replaying WoTR (custom Core) with its 6 difficulty levels (plus custom) and non dumbed down ruleset. Add to that the six person party, a dozen or so companions, more classes and subclasses than you can shake a stick at, choice of TB or RTwP (I prefer the latter even though it makes the game more difficult), loot that is useful rather than gimmicky or ridiculously situational, etc, etc, and you have a far better game than BG3 will ever be - Definitive Edition or no.
Downsides for me are the Crusade part of the game (and the Kingdom building in Kingmaker) and the fact that I don't really like anything to do with demons and devils (or any Abrahamic nonsense).
Edit: And for the two Acts of BG3 that I played before I lost interest I used mods which gave it 5e and RAW rules precisely because of the idiotic things such as throwing potions listed above.
