Mookie asked me earlier: "Which would you want? Permanent invisibility or the ability to fly?"
Sad thing is, i knew the answer because i thought about it already. Then again, i'm a dork.
The problem is that either are useful at times and not so useful at other times. Both can be "turned off" in various ways (e.g. lots of clothes and makeup for invisibility vs. not flying) but obviously one can be turned on and off a good deal easier.
Of the two, i'd pick flight. Invisibility just seems like too much of a hassle. Yeah, sure, you can hang out in changing rooms whenever you like and in theory, never have to worry about paying air fare costs ever again, but lets face it, you're naked all the time, you stand out in the rain (literally and figuratively) and while you're not "visible" you can be detected in any number of other ways (e.g. pressure sensitive plates, CO2 detection, echo location, etc.) You just get a false sense of security.
With flight, you have an avenue of escape that's unavailable to many others, can be disguised (e.g. fake a talisman to give your enemies a focus instead of you.) That sort of thing. Plus, you can get stuff off the top shelf without a ladder, and you are the perfect sniper position with an immediate way to get out.
For what it's worth, if i'm going to have any single super power, i'm going for mind control. Make folks forget they saw me, have a bunch of them carry my stuff, set myself up as a benevolent dictator of some country, i tell ya, it would be the good life.
