For all the complaints about DS9 being tied to the station and then using Defiant as a vehicle, IMO it had the best character set of the Treks.
Quark, Nog, Odo (esp with Gene's wife as a foil), Garak *watches a Garak clip for fun, sigh- now I need to make a tailor for Galatea or Solaris VII*, Dukat, Weyoun, Martok, Kai Winn, Zek, Morn, O'Briens, and Bashir.
