It might seem great to have superpowers. However, it is likely there would be some downsides.
As an example, having X-ray vision might seem to be a wonderful thing. However, in the book "The Phantom Tollbooth" by Norman Juster there's a character named Alec Bings who sees through things. The problem is that he keeps running into things like trees because although he can see the tree behind the one in front of him, he can't see the tree in front of him.
Another example is Ultra Boy (a member of The Legion Of Super-Heroes), who has the same powers as Superman with the limitation that he can only use one at a time (his actual superpower is ultra energy that he focuses in a direction, focusing on his muscles gives him super strength, and so on). One time he used superspeed in an atmosphere and he caught on fire due to air friction since he can't use invulnerability at the same time.
Finally, there's Cyclops (a member of the X-Men) who has the extremely powerful optic blasts. The problem is he can't turn them off (the only materials which block them are ruby quartz lens and his own flesh), and so there's always the potential that he could cause massive destruction.
