In no particular order:
Blakes 7
Babylon 5
Farscape
Those three are out on their own. I usually describe B7 as my favourite, as it (along with classic Who) was the show that really hooked me on SF, but the other two are just as great IMO.
classic Doctor Who (new Who has never appealed to me in anything like the same way the original did and still does. It's safe to say that if new Who had been my introduction, I'd have stopped watching pretty much straight away)
Lost
The Twilight Zone (original)
TOS / TNG / Voyager (I like them equally)
The Avengers (the Emma Peel era, when the show was basically SF).
