I always liked Uranus and Saturn as my favorites. I used to play the RPG and action sidescroller for SNES on my computer, and those were quite interesting especially the RPG when you had to deal with old enemies being revived and the Anti-Senshi who basically nullified/opposed powers. Also I'm reminded of a Animerica poll of top 100 hottest anime females and remembering that Uranus was number 4 on the list.
