Ezri/Bashir was boring. I honestly and truly didn't give a rat's hind end about them as a couple, and I don't buy into Ezri's line "if Worf hadn'tcome along it would've been you"; Jadzia was about as into Julian as Picard was into Lwaxana. But I will admit, given that Bashir got dumped for a Ferengi, they had to give him something.
On the other hand, while I know it was impractical while they were flying home, I liked Janeway/Chakotay. Not going to say they're my head canon pairing though... if I did that, something would probably happen to louse it up.
