If you talk design alone, sure, whatever floats your boat. But gameplay-wise Blaziken is the single-most useful and powerful starter of all, not just fire types alone. Its even banned from most competitive tiers cause its so broken. -_-
Of course I'm talking design alone, that's what matters when it comes to liking a Pokémon or not. And Blaziken being the best starter ever is debatable, since Greninja exists. Then again, I never found either of them to be as OP as people make them out to be, they're honestly not that hard to deal with. And then there's Mega Charizard and Mega Venusaur, which are both pretty insane as well.
