I don’t want to tell anyone to have fun, so I’m not saying there’s anything wrong with that, but wouldn’t you have enjoyed it more if you had waited for a complete product before playing it?
I understand that sometimes the answer to that is no. For instance, multiplayer EA games are often in early access for a long time, and on some, most of the most active playerbase was during EA, and by the time it’s out it’s past its peak. So I get that. Or games that are almost ready, but just EA for a few weeks or months to polish and add features - it’s probably better to wait, but you’re getting most of the experience.
But with story driven RPGs - I don’t know how much content the game has, but I know the EA periods in the previous Larian games - you could only progress so far into the story, the inter-character dialogue/options were spotty, a lot of side quests and content were blank. It seems to me like watching a movie as they film the scenes, releasing one scene at a time, sometimes without special effects, sometimes without the dialogue being fully written out. And hey, the movie and characters are so cool that you still manage to enjoy it piecemeal, but the whole it would be better to experience it as a cohesive experience.
If you disagree and enjoy it anyway, that’s fine, but since the OP was asking about whether he should get it in EA, that’s my opinion on that.
