That's an interesting matchup! You should make this a vote; the results would be even more interesting!
Yes, I hate to admit it, but I too think the Green Guys have the edge over the wall crawler, in sheer numbers alone. Although it wouldn't be a quick battle, Leo would probably be the last turtle standing in the end. Spidey would need at least one other superhero on his side to give him an even chance; say, Nightcrawler or Black Panther.
