I don't see how TNG could be more interesting. They had very little character development, didn't really go out and DO anything...the better episodes such as Best of Both Worlds and Time's Arrow were different and good because they took chances and did things. Granted, Q was on NextGen, and I love Q, and I do enjoy NextGen, but compared to a show that had a seven year storyarch and had a freaking war going on (and no, Avery Brooks does NOT overact!!!), NextGen pales in comparison. Besides, it didn't have Robert Wolfe.
And as for that Gene Roddenbery guy...well, GL might have created StarWars, but does he do it best? At some point both Star Trek and Star Wars need to continue without their creators...the Star Trek people have already made the mistake to try to keep all of GR's humanistic philosophies going, but since most of those died with Freud and Stalin, it's time for them to move on to greater and better things...like story instead of message.
Yeah, I can't say that any of the characters on DS9 are memorable at all (except for the TNG ones that make guest appearances), but they're both okay series'.
