DannyHamilton is very knowledgeable. He is the type who can confuse you with his technical know-how and the way he explains things. He often writes lengthy walls of texts, but they are posts that are interesting to read.

franky1, on the other hand, writes walls of text that are impossible to read. He doesn't respect anyone's opinion and is only interested in what he has to say. It takes a lot to be banned from posting in certain parts of a forum that is as free as Bitcointalk, and franky1 has managed to do exactly that. I wouldn't classify his as an unsung hero, but as an anti-hero as someone already suggested.

I can't say that I know much about JayJuanGee because we aren't active in the same subs. According to Ninjastic.space data, almost 90% of his posts are in the Speculation board.
