Darth Malgus vs General Grievous

This is Deceived era Darth Malgus vs Revenge of the Sith era General Grievous. This is a lightsaber fight, the Force can only be used to amp physical abilities and for precognition. Fight is to the death and it takes place in the Jedi Temple. Who wins and why?

@nfactor1995: Didn't you already make this?

@thevivas: If I did, I couldn't find it anywhere and I honestly can't remember.

In a sabers only contest Malgus dies.

I feel like Malgus could last longer than 20 seconds against Kenobi, so he would probably win.

If this is Legends GG, it might be a tie. Though he fights jedi, not sith (who are less restricted).
