it's hard to tell since both have the same power and go through the same things, but probably Diana since she is a major fairy while Flora is a guardian fairy

^Yeah coupled with the fact that Flora always falls first so my choice wasn't to hard. :)

Yes, I agree with you. And also Diana is more experienced than Flora so...

....

Only because she is more powerful, but I love Flora more.

Diana is the major fairy of the forest, and she knows how to use her nature powers. Flora just flings wimpy little vines or flower petals the majority of the time. Diana almost turned Gardenia into a forest. Plus, her vines zapped Flora of all her strength--and Flora is the one whose supposed to be "one with nature".

Who the hell picked flora?

She would win for sure.

diana is very powerful shes even more powerful then the winx but the winx have to earn there sofix so the winx are as powerful as diana

But usually I love Tir Na Og because that's were Roxy lives.

I think Flora is more powerful because she is the second most powerful fairy, she is just shy and sensitive, I think if she gets a little serious she could even beat bloom (bloom is the most powerful fairy).

And it was also told by the winx creator himself
