What I am saying is that they all follow the exact same formula. They all follow the exact same trope; it doesn't matter that their goals are all different; it's that they are all written to have a hidden agenda that conflicts with other party members' goals, with possibly the exception of Laz'Ael, who's just boringly angry at everything all the time.
And I like the character of Astarion; I don't necessarily like him on a personal level; it's just that so far, he is written SO much better than all of the others.
On top of which, they all appear to be written with only their relationship to the PC in mind. There's nothing so far like Minsc/Dynaheir or Octavia/Regongar or Edér/Xoti.
I agree that they are all similar in that regard (except maybe Laezel), having a hidden secret is a blatant similarity between companions. At this point I am pretty sure that it is the case for a particular reason that will be revealed later in the game.
For Astarion, I agree that his character arc is pretty well developed in early access. I would argue that Shadowheart is too since she gradually opens up to you during the course of the game. Hopefully other companions will have similar treatments (looking at you Wyll, I barely know you).
I also agree that CRPG, and BG3 in particular are quite horny. This is what people want apparently, every time there is a new character there are also hundreds of people talking about romanticizing it...
