Both female companion work very well from my point of view. A few hours into the game and I already hate Lae'zel with a passion and I'm intrigued/disgusted with Shadowheart. Which means, they provoke an emotional reaction in me as player. My current problem is more like, that every NPCs so far provokes at the very least a mixed or negative reaction and I can't see myself romancing (or playing) any of them.
