This is quite an easy choice. Many people have impressed me but I can't say I stylistically stole anything from them. FriedRice to name someone less mentioned. Also Kamiko who raped Toriolympics hard. And generally these people who pushed Toribash to new limits and redefined the 10/10 rating.
I'm surprised my top choice hasn't been named yet though. For me, that is definitely Dafe. That guy was so far ahead of his time. I don't see anyone matching his all around awesomeness. His replays are as ferocious as his scripts and ingame skill.
