The problem with comparing the Rogues to another hero's villains is that the Rogues are so unique, especially with the way they're written these days. As a longtime Flash fan I enjoy the individual character's histories and personalities, but they act as a single unit and they don't (or aren't supposed to) kill, so they're operating on a different wavelength than, say, the Bat-villains. It almost seems weird to break them down as individual bad guys anymore. There's not Captain Cold AND Heatwave AND Mirror Master AND Trickster (and so forth), it's just... the Rogues. That seems to be DC's preferred method of packaging them, anyway.
