DS9? Best or bestest Trek? Corrolary; Sisko? Best or bestest Captain?

It’s been a long time since I watched DS9, but I remember it as being somewhat richer than TNG, because of the way that the space station location allowed them to do some great Casablanca-style plots, what with the aftermath of the whole Cardassian/Bajoran thing. Don’t remember being that fond of the whole wormhole/savior stuff, tho.
