I don't know much about either man. However, if I had to vote on the basis of their ad campigns, I would pick Christ. Gallagher seems demogogic to me. Also he just sent me a bumper sticker out of the blue with no info, at all. Harris is doing a very good job of following up on contribution with newsletter, by contrast.
Crist is.
The Gallagher camp is very pleasant and it sounds like you have never visited his web site or emailed them to see how accommodating and organized they are.
Brett Dozier was Jeb Bush's campaign manager and works for Tom G. Crist's campaign mgr is a developer's son. Crist is fuzzy on eminent domain - gee, wonder why.
