Gotta go with Flight 2000, although Seawitch is a close second. Meteor is licensed. When you see the copyright on the backglass, it says something along the lines of "1979 American International Pictures."
Flight 2000 for me with Catacomb a close second.
Meteor! Looks more exiting. All of them seems like borin to me so. Meteor it's the cream of the crap.
