Typhlosion vs Blaziken
These two don't really have much in common. Their comparison is largely similar to that of Charizard vs Blaziken, ie: Typhlosion is faster but Blaziken is stronger and both are Fire Starters. The difference being that, unlike Charizard, Typhlosion doesn't have a type advantage against Blaziken.
They were both mercifully blessed with excellent Dream World abilities. Typhlosion gets Flash Fire, which gives it an immunity and a power boost when hit by Fire moves, Blaziken nabbed Speed Boost which is exactly what it says on the tin.

Typhlosion is my second favorite Fire Starter, that said, he's a very distant second. Blaziken is still miles ahead of him in every category for me. Not to mention he'd wipe the floor with the hedgehog. As much as I love Johto, I have to give this match up to Hoenn, because they came up with an excellent Pokemon right here.
