Would you rather have the ability to fly or be invisible?
Hmm... both are pretty tremendous.
I think I'd say fly. Not that being invisible wouldn't be all kinds of awesome too.
Definitely fly. This reminds me of a joke:
" Superman was feeling bored after a long streak of crime fighting and wanted to go out and party, so he called Batman to ask if he wanted to go to a club and pick up some girls.
Batman said Robin was ill and he had to look after him.
A little disappointed, Superman called Spiderman to see if he fancied a few beers. Spiderman told him he had a date with Cat Woman.
As a last resort, Superman flew over to Wonder Woman's apartment to see if she was free. As he landed on her balcony, he saw Wonder Woman naked on the bed with her legs wide open.
Superman thought to himself: "I'm faster than a speeding bullet, I could be in there, have sex, and be out again before she knew what was happening."
So Superman did his super thing in a split second and flew off happily.
Meanwhile on the bed, Wonder Woman said: "Did you hear something?"
"No!" said the Invisible Man, "But it tore my butt up!"
