I picked Picard as an overrated character. He was boring, self-righteous, and a bit too over dramatic. (Some people like that. Unfortunately, I wasn't one of them). Although, I'm surprised that Data and Riker are going neck in neck.
Data can be cheesy if not handled well (e.g. Data's Day, the bits in Generations, etc.) but he's an interesting character when handled correctly (e.g. the 'toys' one where he gets so angry he's about to shoot his captor, then brushes it off when he gets back to the ship).
Riker was always 'meh' to me. He didn't like it when Deanna dated out, even when they weren't officially together, yet he was always written or hinted at dating or sleeping with women. He was also a bit by the book when he wanted to be; he was one of those who very much liked his authority and would exercise that authority just because. (As I type this, there is a 'Riker-like' character I knew of who was a former boss. I didn't have a problem with him, but I knew other employees who did. Too, it's interesting that he actually did move from a 'second-in-command' position to a 'commanding officer' position after the year I knew him).
