Usually the females (whether Pros or celebs). They tend to wear the most eye grabbing costumes and do alot of the pretty flourishes of routines on top of the main dancing. I tend to overall naturally graviate to what is pretty or eye catching in some form. Of course I keep an eye on the male celebs with their progress, but I tend not to engage with them as much in entireority (is that a word?). With females I watch and engage (more often), with males I watch and there is less often the connection, it's just the action of watching. If a male celeb is that extremely good, on exception i find myself enaged there too in full. You can't help what you swing to.
I tend to take real notice of the males in partnerships where they've been made the joke couple of the series i.e. usually in most cases Anton, I tend to watch him just in order to appreciate what a slog it must be year after year doing little dancing yet still having to work so hard.
