I wouldn't say I particularly like either, other than some nostalgia and appreciation for introducing me to Sailor Moon... However, I actually think I have a slight preference for the Cloverway dub. I agree that the DiC dub is more polished -- however, I preferred the Cloverway dub for having a slightly more faithful script and keeping the original musical score. DiC didn't even feel like the original show, whereas Cloverway more or less kept the "feel" of the original show intact and I feel a huge part of that has to do with the music.
That said, I still dislike Cloverway for their changes to Haruka and Michiru's relationship. But I have fond memories of being a kid and how excited I was when S premiered on Toonami for the first time. Before that, I'd only heard of the S season (not sure why I never bought the fansubs) and couldn't believe there were new episodes on TV, not to mention how exciting the storyline was.
