I wrote a big long rumination of Voyager (mostly a defense) a little while ago. Realized I never posted it anywhere, but this thread reminded about it. You can now read it here. As a summary, I believe the actually quality of the TNG era Star Treks are the exact opposite of what they are generally accepted to be. Actually I don't believe I address DS9 in that essay, since I hadn't done my rewatch at that time, but I think the series is pretty awful for the most part and I'd rank it below both TNG and Voyager.
