Data, I imagine myself as him sometimes, because I rely on a wheelchair its nice to just think myself as Data, although Ive been unabe to watch all TNG episodes the ones I do get watch I think are amazing. O an just for the record my brother I consider Lore cause he can be evil when he wants to be..... HAHAHA
I liked Worf. He had his funny moments, and when they happened they seemed to be just borderline extreme, and some of his one liner comments were funny. I also liked Chief O'Brian for the same reason.
In DS9 both, Worf and O'Brien had the opportunity to expand their roles - and I loved it sooo much! DS9 is, for me, the FINEST TREK I've ever seen to this day. TNG is the best, but DS9 is the finest one. There's no ST series with more character developpment. than DS9 . And this goes for Worlf and O'Brien, too, of course.
Well, I never liked DS9 as well as TNG, so it took some getting used to. Worf was still funny, but his character was much more serious on DS9. I thought Quark was way better, although Worf did still have his moments. And the Chief seemed to remain the same on TNG as well as DS9.
