My personal favorites are the ones with limited entries, some subject that is at least a little bit obscure, and where you can vote for as many as you like, but that's just me. The really general contests usually have way to many to look at individually. I do like to vote for more than my own. I consider it a little bit of an "honor" thing, but if it takes an hour to scroll through because there are so many, I generally rely on the thumbnails, which really isn't fair. You don't get a good look that way.
