I very much like SH, Lae'zel, and Karlach. I have a certain appreciation for Astarion and his sneering upper class drawl. I like Gale a bit less than in the EA. Lae'zel has more nuance now than in the EA, and I just mentally picture her as my party's resident Klingon. Karlach is just fun. She's up for anything. Wyll is possibly less interesting for being made more heroic instead of genocidal (towards Goblins). Of all those, SH is my favorite. Her story progression feels vital and real.

Jahiera is fabulous. I like her world-weary leadership vibe. Minsc is... well, he is a lot. I like him in small doses. He is well-played though, if a little over the top.

I'm just getting to know Minthara on my second playthrough. I haven't got a good read on her yet. She might be a psycho, but maybe not. Can I fix her?

The one I really don't care for at all is Halsin. He's just a big dumb boy scout, and it feels like he just tagged a long to shirk his grove duties and get laid.
