Wikus van de Merwe in the Mech Suit vs. Mark 1 Iron Man

They fight in the slums of District 9. Wikus is clear-headed and not delirious. His level of control over his suit's abilities still at the rudimentary level shown in the movie.

He doesn't need fancy manoeuvres to point and shoot though.

Who takes it?

Stark, I think, on speed and manuverability and having a devastating arsenal that looks capable of inflicting massive damage on Wikus. Certainly enough to debilitate the suit.

Agreed, the flying, maneuverability and speed is a huge advantage for Stark.

Though that electric-like blast that turns people into the insides of a Suet Pudding might be a tide turner.

And I just realised that it's Mk1 suit too.... Less manuverability and speed than initially projected...

The Mk1 suit that Stark made in a cave with a box of scraps?

Yeah, Wikus stomps that thing.

It's the 'junk-yard' armor? Shit, thought it was the silver suit he first made in him home-lab.

Yeah, Wikus takes this.

Agreed.

The Mach 1 armor was designed to burn men, repel bullets and make a flying escape.

spite.. no way Stark's cave man armor wins here
