TNG for me. I prefered the writing and cast dynamic over the other series. Cept for J. Franks *ejects him into space*
After that I'd have to say DS9, TOS, Enterprise, and lastly Voyager.
As for the movies, pretty much the even numbered ones; Wrath of Kahn, Voyage Home, and Undiscovered Country. 1st contact was Okay, but other than that I try and forget the Next Gen movies exist, expecially Nemesis.
