I prefer Natsu, because he's funny, he's using fire magic or rather fire dragon's magic, which is quite unique and really strong, he have hilarious weak point - he can't stand transport, so when the floor is moving he's easy to beat ^^'
Although Gray is awesome (my second favourite ice user in manga to Hitsugaya) I voted for Natsu. I do usually have a preference for the main hero (for example Naruto, Goku and Luffy), but this isn't fanboyism. Natsu has the cheerier personality thus I prefer him.
both are great characters, but gray is almost constantly stripping, that a little wierd, sure natsu suffers from motion sickness, but thats preferable to someone who strips randomly.
plus natsu is one of the funniest of characters, but when it comes to a fight, especially about his guild or friends, hes serious and doesn't like to lose, he refuses to.

Hey... the results here are not quite the same as the "who's your fave member". natsu leads here while Gray leads in the other one as Gradonil_Ral says. Possibly those who voted for someone other than the two of them picked Natsu in this poll?
I still like Gray better. He and Natsu are really hilarious whenever they fight. They seem to be different (one is an ice magic user, the otehr fire) but they have some similarities. For instance.. both like to charge straight into battle
