It's hard for me to say but i would bet on Leroy although if Sagat went to tekken world he would probably be stronger and could win.

Maybe.

But I’ll say Leroy as well. He’s faster, smarter, and more precise. Sagat has tendencies of being aggressive and headstrong.

Yes but in terms of pure strength and techniques Sagat could have a big advantage guy literally control fire.

Well, energy, but yeah.

Leroy Smith (Tekken)
