I have to admit, while I am a lifelong trekkie (I actually do like all the series and most of the movies up till now), I gave up watching Enterprise. Even ignoring the crap theme, I haven't seen one good actor on it, and thought most of the storylines in series one where distinctly lacking in imagination. The Special FX are good (which means visually it doesn't match with either the original series or TNG) but most SciFi shows have good SFX now.
As for Babylon 5, I also love that, but for different reasons to Star Trek. One thing I did like is the extended story arcs (an idea which the DS9 writers copied with their Dominion Wars arc, which I think made ST
S9 better). Star Trek seemed to have more fun elements, and in some cases, better acting. B5 was a better drama which took it's time to develop stories.
