Like I said, it depends on if Wormwood gets involved, Matt COULD win if he plays carefully and beats Eggy without putting him in a situation where Wormwood wakes up.
The one advantage Matt has is that he can choose when to use that power as opposed to Eggy, who usually needs to be forced into it.
Collector has more overall power, Nova has more experience and Collector is a bit reckless at times, so Nova could win if he plays smart and Collector makes a few stupid moves, but other than that I don't see Nova having any other advantage.
Collector is stronger, faster, and his power has more capabilities than Novas does.
