For Trek DS9 ended up the best series due to them seeing what B5 had done with a story arc planned well in advance and they copied it, as said above. Overall B5 only just edges it for me but not a lot in it as both i could watch again and again, which i tend to do seeing i own both DS9 & B5 on dvd now. I could watch either of these series in the knowledge they are both great and i will not regret watching them.
It is just a pity that JMS had the TV studios mucking him about, as series 4 and 5 of B5 could have been so much better if they didn't have to rush 4 to finish the shadow war off with the threat of cancellation over their heads. Hence series 5 being poor in comparison to the previous 4.
Oh for another JMS B5 related series with a studio brave enough to go ok here is the cash do as you wish we wont muck you about, unfortunately not many in the US would ever take that risk and if they did would cancel it if viewing figures weren't high enough
