IMO the Io sets are really good looking, same with the titan sets, except for, ironically, the titan set from titan. I like the warlock Nessus armor. Wildwood looks like shit as always of course. Eververse armor looks good across all three. I don't like the crucible set for warlocks but it looks good on titan and hunter. The Ikora sets are nice and all, but they just look kind of... flat, less detailed. Vanguard armor is okay but not my favorite. Trials armor looks amazing, except the warlock helmet, it makes you look like your going to the rice fields.
