Kick off return question?

[Stingrayred]

If the ball is kicked into the end zone, does it make sense to return it? It seems to me that taking it at the 25 is a better alternative unless you have a super returner. Most of the returns I have watched either don't make it to the 25, there is a penalty that moves the ball back to before the 25, or it is fumbled. There is also the chance of injuries. Does anyone have any statistics on this matter?
