I put Spider-Man on top here, with honorable mention to Daredevil, Captain America, and Nightwing
Don't forget Nightcrawler.
Just like energy projection, this is a hard one to figure out. I've noticed that the two most overused powers in comics are flying and throwing zaps.
Perhaps judge by where they are limited to flying. In this case, Heralds can fly in space - and hyperspace - and even through time.
Best at Healing
I think it's Wolverine, with the Hulk a close second.
Don't forget Madcap - who beats them both.
Spider-Man shows this in his solo books more often than anyone else. After that, I'd go with Captain America, especially while he's leading a team.
I'd like to throw a vote in for the Punisher.
Reed Richards in first place. Hank Pym, Tony Stark and Doom tie for second.
Plus, it's kinda Forge's whole thing.
Captain America hands down. He's both inspirational and leads by example. (Something Superman btw is not so good at.)
Bruce Wayne, Tony Stark, Lex Luthor, Norman Osborn, Doctor Doom. Place those in whatever order you want.
Here's my order:
Tony Stark, Lex Luthor, Norman Osborne
The Kingpin (at his height)
Warren Worthington III and Janet van Dyne
Daredevil. Since stealth is more about being silent than being non-odorous, Wolverine can only get second place at best. After that, Batman, Nightwing, Electra, etc.
I'm throwing a vote in for the Spot!
The Hulk, then Superman
I'd say Superman is above Hulk when both are at base levels, but Hulk will get stronger and surpass Supes.
This is the only one I can think of where Wolverine comes in first. Unless you mean tracking as a detective does, in which case Logan would be way behind Batman.
Or there was Caliban (although only mutants).
