Meh, this is a tough choice for me...
Salamence's cool looking, and better at battling, everyone knows that, it's movesets are just awesome, whether it be Specsmence, Mixmence, DDmence, CBmence... Just... Cool.
Flygon... I just love the thing, the way it looks... I do like its movesets, but of course they're not as good as Mence's, but still...
Man... Yeah... I think Imma vote for Flygon... I don't know what it is... But Flygon's just cooler to me.
