I used to hire The Next Generation episodes on video as soon as they came out (2 episodes per video) - but I've never really got into DS9 or Enterprise. Voyager was pretty good at times - especially from when they came across the borg - but the cast and storylines from TNG still win the Star Stek "best series" award IMO.

With decent writers on sci fi programs like Stargate now, its not a surprise that a series like Enterprise where one fairly shallow storyline lasts a whole season is having trouble getting audiences.
