This is a hard one. There are just soooo many to choose from. Almost had to do a bracket to narrow my choices down. But I finally decided on:

Jar Jar Binks

No, not really. Just messing with you. After much meditation and thought, I would have to say that my favorite character is:

Han Solo

From the moment you saw him on the screen, you knew this guy had swagger. Confidence, a hint of arrogance and (after he shot first) a bit of aggressiveness. His best bud is an 8' walking carpet that only he seems to understand and he has the coolest ride this side of the Tingel Arm. He has everything under control, is full of surprises and never wants to know the odds. He survived betrayal by his friend, being tortured by an asthmatic Sith, as an ice cube ornament for a gangster and losing his vision (temporarily). He also has the greatest one liners. In the end, he gets his eyesight back, his ride (minus one rectenna) back, his friends back and he got the girl. And we haven't even touched on his expanded history in the EU*.

I had the opportunity to talk to Han before I wrote this and told that he topped the list as my favorite character. His response was all Solo.

* - I don't care what Disney says, the original EU happened.
