I'm going to have to go with Glowhoo. It used to be one of the most worn shaders in the game and I can guarantee that it is my most used shader. It looks good on everything and was the one shader that made my favorite exotic armor, Glasshouse, look good. I loved how bright and... glowy... my Warlock and Hunter were, and how shiny my Titan's gauntlets looked when I melee'd that poor Vandal in the face for the thousandth time. It also took me the most effort to get. I spent at least 10 hours with many different raid teams over the course of 3 weeks trying to beat hard Crota. It was worth it.
-The end.
