Hooker Cena_mark is one of the most interesting trolls I've ever seen, not for his inflammatory remarks, but because he tempers it with these little seeds of doubt that he actually has a legitimate personality, is trying to fit in, and has a personality beyond his ludicrously over-the-top political views.
Hooper_X He's got a fair bit of depth for a troll. Every once in a while he drops little bits of backstory or plays along in a very convincing way.
What I'm saying is that his trollcraft, while not necessarily welcome, is at least of solid quality.
Baldr He's definitely Baleen. But even Baleen's trolls are more entertaining than some of the other people here.
