Babylon 5 is too overwrought with a lot of early and late misfires for it to be on par with DS9 even storywise, but it's sublime when it gels and hits its stride. Even in the 90's the show looked rough though.
SG1 is the true Trek disciple IMO. I also rewatch Farscape and other shows more than I do B5, but it's still a great show. A modern remake of B5 would grimdark and cut up the entire show if Straczynski allowed them to. Hope it doesn't happen. Koenig was great in B5 also, one of my favs from TOS.
