Josh Holloway - no brainer, Sawyer is one of my favorite characters on LOST, and he's HOT. My fiance agrees, he finds Matthew Fox rather annoying lately on LOST, although I remember him on Party of 5 and I was a fan. This topic nearly got me to make first call into a podcast, alas I am at work so something else will have to fire me up to call in.
I'm not a big Matthew Fox fan. I don't really like most of the characters he's ever played. In real like, I like good boys. Josh Holloway has an awesome accent... I miss living in The South. I love that the authors have the character of Sawyer reading anything he can find because that's how I am.
I like Josh and the character of Sawyer, but no question Matthew will be the winner. Matthew has a better resume. The other thing is that if Sawyer carries a log we will all be sad, but show will move on. You will never see Jack carrying a log. Jack has to be flawed to be the hero. We would all HATE his character if he was saving everyone and was flawless.
