Would you rather be able to fly or be invisible?

I’d rather fly. Being invisible allows a person to be hidden indefinitely, however I think flying is much more useful. IF the goal is to be hidden, you could easily fly to someplace where you’d be alone. If you are trying to spy on someone, being invisible would be the easiest method, however you could easily spy on someone while flying as well. Also, if I could fly, I wouldn’t need a car which is nice because then I wouldn’t have to pay for gas and it’d be safer as well.
