I've owned both, ST:TNG for nine years and ST for two. I sold ST:TNG two years ago and haven't missed it. I sold my first ST (a prem) after a year, kicked myself repeatedly, and bought another (pro). It will be a long term keeper. I find ST to be better in nearly every way. I also think it is the most geometrically perfect game ever designed. ST:TNG is very good, but I burned out on it and now really do not have much urge to play it. ST is a game I play often and still crave more.
