I'd say yes. Both games are fairly good. I used the companion banter packs for BG1, because there, companions have not a lot (if any) banter. And the tweak and fix mods are fairly good. Other than that, I wouldn't use a lot of mods on the first playthrough. Later maybe Unfinished Business, which restores some quests.
You find some elittle nods to those games in BG3 - so far I found mentions of some companions (Dynaheir, Faldorn, Minsc for example) and events.
