I think Wing Zero win, mainly cuz I favor Wing Zero over Eva 01. But I speculate that Heero is a great pilot, his character is, "I must complete my mission at any cost" Granted that, he makes a great pilot. As for his Gundam, I would assume his artillary is strong enough to penetrate and destroy Eva01. He destroyed a colony once, and it was at space! It requires a lot of force to move anything in space. Wing Zero's speed is at least 10 times faster than the Eva. Zero got flight capability as well, thats a great advantage.
However, the Eva shouldn't be taken lightly. The Eva can still kick ass. Despite its greater size, strength, and AT Field difference. I doubt its artillary would be able to defeat Wing Zero.
If anything goes, All Wing needs to do is to be cheesy, and shoot everything he got in the air where the Eva can't reach him, then run away and reload lolz. OR he could try to destroy the cable.
In a fist fight combat, I think Eva would win hands down.
