I like Lae'zel. She's young, has been brainwashed for all her life and Creche Ka'lir (probably spelt that wrong) was pretty much the premier Creche relating to Toril so she has an inbuilt pride and arrogance deriving from her upbringing. But as part of that she is also very honourable - not trying to ditch you outside the Creche but insisting you go with to be cured as well. As far as she's concerned the creche is the only way to cure you all - it's what she has always been taught. Her heartbreak with the events regarding the Inquisitor is her whole world crashing around her, would have been easy for her to just blame you but instead she picks herself up and helps you to carry on.
My dream team for playing this game is Astarion, Shadowheart and Lae'zel. Rogue. Cleric and Fighter which means without even respeccing at all I can more or less pick whatever I want to round out the party as I feel like.
All three have strong character progression throughout the game, depending on your choices with any of the three you can alter their perception of the world in substantial ways. They all have some hilarious interactions and snark in the early chapters. And all three have interesting personal quest lines.
All the rest I pretty much ignore, either leaving them in camp whenever that is possible or not recruiting them in the first place.
