The two aren't really comparable, IMHO. I love them both, but for different reasons. Barnabas (except for when he's bad) is like a benevolent uncle whom you'd turn to in scary or tough times. He'd be a faithful friend and an interesting conversationalist - I could listen to that voice of his all day and night.
Quentin on the other hand, you cannot rely on for a thing - except to follow his own (usually prurient) interests. He's totally gorgeous, but as we see him now on the show he's a selfish bad boy. Granted, that can be attractive, but only for a limited run.
To sum it up - for a confidante or for someone to have my back in a supernatural throwdown, I choose Barnabas. If it's a night of kinky passion, it's Quentin all the way!
