We each have different tastes, perhaps part of the feeling as to why DSN is/was considered mistreated stems back to when it was first announced/produced. Star Trek on a space station how will that work, they won't go anywhere etc...
I would say both TNG and DS9 had a hard time gaining acceptance with fans when they were first announced. At that time when TNG was starting out, many TOS fans were saying it wasn't Trek without Kirk or Spock. The first two seasons being so weak really didn't help either.
ENT also had a really rough start with fans with the whole prequel thing.
VOY had it easy compared to all the other spin offs.
