Well, if I had to choose between those, my vote would definitely go to TNG. However, if you had put Enterprise there, I would have given it second thought
As you are a TNG fan I presume you dispise Enterprise, but I had to say it...
As for the others, Babylon5 was just too "cheap" for me and couldn't keep my attention long enough. So, The Next Generation it is, dispite of all its flaws :wink:
