I only have one DCQ pot (bought from a member here, actually). It's one of those private order pots commissioned by a Malaysian collector in the 90s that EoT used to carry. No idea to what extent the fact that it's fired in a dragon kiln makes it different from other DCQ pots, and since sample size = 1 I wouldn't dare generalize anyways...
But I really like it! Works well with a range of teas, particularly when "you want to emphasize body over nuances" as
@steanze said.
I've actually been on the lookout for a larger DCQ pot myself (something in the 180+ ml range, preferably fired in the same way since I'm so happy with the one I have), because many of the teas I find work well with my current pot are teas I enjoy as office drinkers.
