Well, I like the show, so of course I'd say "watch it!"
But, honestly... it doesn't have much bearing on the TV timeline (the books and Star Trek Online timelines do depend a ton on the events of VOY, though.) A few developments happen in the AQ, but nothing important.
Well, uh, okay, the development in the last episode was kind of extremely significant. And that one time they saved the galaxy. But other than those, no.
If you don't like it and are just watching so you don't miss anything, you can probably skip it.
