"Gross" or "Shock-Jock" items have a very steep hill to climb in this competition.
I'd add overly "evil" items are challenging as well. A variation on the "item being for both the GM and PC" lesson. Having a CL15 magic item that gives you negative levels (or just horrifies the townsfolk) is a frustrating tease.
Barring access to a temple with a "Trade your Evil for Good, or GOLD!" policy, it'll just sit in the portable hole, or it'll be tossed into a volcano.
Great for MacGuffins, not so great for treasure.
