I'm working my way through a second re-watch of Q-Less right now, and have been struck with just how underrated this episode is, and how important, in the long run, it is for the evolution of Q's character and how much it foreshadows his later appearances on Voyager (particularly The Q and the Gray and Q2). The way he interacts with Vash is, IMO, very much a precursor to how he interacts with Janeway in both of those episodes, and it's also just fun to see him try to get under the DS9 crew's - and Sisko's - skin and how Sisko isn't having any of it ("You hit me; Picard never hit me"; "i'm not Picard" is a great sequence played to perfection by both John Delancie and Avery Brooks).
