That's interesting you say that about your DS9 rewatch. The very first time I watched through the Trek series DS9 was my all time favorite. It wasn't until I rewatched Voyager a second time did I begin to gravitate towards voyager. And beyond that I just finished TNG and Voyager a couple weeks ago (I don't have a streaming service at the moment otherwise I would be going through DS9 right now) and it seems the more I go through each series the less gravity I feel towards any of the three in terms of deciding a favorite. I'm glad you can see the flaws in it. I am in a couple Star Trek Facebook groups and one of them for DS9. For some reason I find it more difficult to speak in that group than others. For some reason in my experience DS9 fans have a difficult time excepting the show does indeed have flaws. Don't get me wrong lord knows Voy and TNG most certainly has its flaws but it annoys me when I point out poor writing decisions and people still argue it as "groundbreaking". There is nothing wrong with DS9 being anyone's favorite (so long as it ain't Disco and Picard lol. If you want flaws look no further). It deserves to be a favored Trek but that doesn't mean it doesn't have its problems.
