Lae'Zel is actually my favorite of the companions.
For one, she is the one that actually drives the main plot; without her - there is no stake in the whole choosing-at-the-end. She is rather rude, for sure... But I kind of respect an honest person that just flat out says what is on her mind. Also, she gives as good as she takes. She actually respects you for it if you stand up to her. I love debating our respective noses.
Now then, she is by no means the most unlikeable character ever created in a video game. Off the top of my head, I can name a bunch from roughly the same genre that would qualify well before Lae'Zel does.
Preston Garvey, Dandelion, Disciple are all waaaay worse. Hells, she's not even the worst Gith Follower in D&D Adventure games, because Zhjaeve was in Neverwinter Nights 2 and she is *the most annoying ever*, "Know the knowledge that is known to be known when its known!"
Lae'zel's not even the most unlikeable character in this game, because the Emperor is in it.
