Invisibility: and be even more ignored? No way
Ability to fly: with the current fly prices? Not needed
Super strength: ye sir, give me more!
Seduce any women: what about men? just kiddin, no worries guys
I went for the no need to sleep. that would be awesome. Maybe I would be able to waste some time here AND be able to finish some projects!
Invisibility: Doesn't extend to items, and having subvert access (without taking things away) is rarely profitable or useful. Read a few wonderwoman comics and you'll quickly see that its not all that useful.
Flying: You'd be poked, prodded, examined, and constanly be labelled a threat to national security. Net negative overall, and really, who needs to fly?
Sleep: Granted, you'd be more productive. A rational choice at least.
Super-Strength: When is the last time in life you would have been substantially better off if you were *stronger*. Right, almost never. Not that useful.
Breathing Underwater: What, are you doing oil platform maintenance? No? Then not so useful. See Flying for other potential concerns.
Night Vision: Buy some goggles. What do you need to do at night that you can't already? Not that useful.
X-Ray vision: Not a doctor? Then not that useful.
Seduction: Now we're talking. People will do virtually anything when they are in love, and there are some rich and powerful women in the world today. Having sway over them means concrete benefits, and not just physically. Power, money, fame, the list goes on. I'm also selectively leaving out the fact that you could be polygamous with Angelina Jolie and Jessica Alba, arguably causing the majority of post-puberty men in the US to kill you on site out of jealousy.
Comes down to Seduction and NoSleep, and to me, Seduction is the clear choice. Just make sure you only take ONE wife.
Invisibility:
NO - I have a wife, five kids, a full time job and a side business. How much more invisible can you get?
The Ability to fly:
NO - I have a wife, five kids, a full time job and a side business. I am flying enough as it is.
No bodily need to sleep:
HECK YES! - I have a wife, five kids, a full time job and a side business. Who couldn't use another 4 extra hours a day?
Super-Strength:
NO - I'm already the strongest man alive.
Breathing Underwater:
NO - Under water is where I go when I don't want to breath anymore.
Night-Vision:
NO - I have a wife, five kids, a full time job and a side business. I already have night vision, x-ray vision, tunnel vision, money vision and boys-at-the-door vision.
X-Ray Vision:
NO - See the one above this one.
The ability to seduce any woman:
NO - Been there, done that. Since she was foolish enough to marry me I don't need this power any more. In fact, I sold it on eBay for $14 plus $395 shipping.
