Dead Island, which is most fun character to play?

I usually dont play though games more than once, so want to get the most out of the game. Which person has the most interesting and varied abilities or most fun?

Purna !

She good with guns, it was a blast playing with her.

Her fury attack is amazing.

I played a little bit with Xian but it wasnt as fun.

My friend and I found Sam B to be the most entertaining by far. He's got some good survivability and some great attacks, so you can really get up close and personal without being as concerned for your safety as you would be with other characters. I played Xian and my friend played the football dude the first time through.
