Name champions who YOU think impress you the most, aka look like they're actually fighting duel style all over the screen. Here are my choices:
Lee Sin: It's a Blind Iron Fist, of COURSE he's going to be flashy!
Fiora: She'll cut you down in seconds and look like a boss doing it.
Irelia: Fun as hell and bloodthirsty, she can just keep coming at you.
Darius: He may not be able to spin like Garen, but Darius is definitely more of a pimp when it comes to combat style. And on top of his flashy moveset, he can turn the tide of an entire teamfight without breaking a sweat.
Akali: Basically what happens if you put a more powerful Ibuki into LoL. Fun to watch, and she'll burst down entire teams in the blink of an eye.
Jax: An honorable mention. He looks really fun at times, but his downtimes are less than spectacular.
Who would you nominate for champions that you really enjoy watching decimate people?
