Which superpower would you choose?

Rules:

Flight - You can fly up to 100 mph, but you would not be immune to pressure, solar radiation, atmosphere thinning, wind pressure or anything else. It wouldn't be strenuous and you could do it for as long as you like.

Invisibility - It is like wearing a big form fitting see thru jumpsuit. You can turn it on or off at will and remain invisible for as long as you like. Of course, you will still be felt, heard and give off a normal heat signature, so Choggie should be careful of snipers with thermal sights.
