Well, again, it's tough to generalize "the best" helmet, because there are variations from the ESB to the ROTJ. The ESB and ROTJ are not as different as was once thought. But, there are differences significant enough for me that a helmet made to be ESB can't be passable as an ROTJ and vice-versa. The "movie-sized helmet" is the best, current interpretation of the ESB helmet. Sarge's helmet, on the other hand, works better as an ROTJ helmet.
