The only series I saw on it's 'first run' was TNG, so it's the one I remember most fondly.
I only saw all of VOY via daytime syndication later on.
I've seen all of TOS, one way or the other, over the many years of my life.
I only saw the first few seasons of DS9, and haven't seen the rest yet.
Only caught a few scant episodes of ENT (which is probably why it didn't last long - Sorry).
Have never seen TAS...yet. Got a few VHS's of the series. Maybe I should watch them?
