Ok, so I finished reading the thread.
Thor, Cap, Hulk, Goblin,
I'm chosing Flash because Quicksilver is no longer a speedster, and he's kind of a jerk.
Lizard
Green Lanturn (it's cooler in theory)
Wolverine (lobo? lol), Namor (isn't this repeated later)
Etrigan (not much for trading souls)
Ms Marvel, Colossus, Strange, Nightcrawler, Panther,
Darkseid, I forgot why I just wrote it down
Captain Marvel
Captain Marvel (sentry's insane), and while Marvel's a kid, he'll grow up
Wintersoldier
JLA, because they're all invincible pansies, much safer if you were to randomly be asigned to a role.
Deadpool, Doom, Iron Man,
Titans, I'm not going to explain myself here
Scarlet Spider
ignoring 3
Daredevil, Sandman, Vulcan, Hawkeye, Rogue, Angel,
Black Mask (damn nazis)
Captain Marvel (Mar-Vell has to spend all day in the negative zone)
Darkseid (Thanos was a living statue, the worst imaginable fate)
Siryn, Deadpool, Namor (repeated) Reformed Pym, Cap, Mr. Fantastic, Toxin, sinister, Gladiator,
Maritan (forget why)
Doomsday (Holocaust dies outside of his suit)
Hulk
JLA (less creepy)
Batman (don't remember)
Punisher, Thunderbolts, MJ (Peter does a better job of keeping her univolved) Colossus
Whie (JJJ is a jerk)
Panther.
There, for the most part I have explained why in each case where I would rather be the DC character.
