Here you go. The old style is on the left, new style on the right. To my eyes, the hotspot of the old style looks slightly brighter than the new style and I feel that it might throw slightly better, but the new style has that great spillbeam.
Some said (might have been Doug from flashlightreviews.com) that with the old style, looking around a dark room was sort of looking at a well lit room through a piece of cardboard with a tiny hole poked in it. It certainly has it's place and I kinda like them, but for general purpose use, the new style is radically more useful.
