A bit like @Salvo Montalbano, there is Star Trek I like and some I cannot stand.
I like Star Wars, but for me it comes down to a few things. First, as a kid I just loved the original Star Trek series and some movies. Then, as I got older and some real peaks/highlights came along, mostly in The Next Generation and DS9, it blew me away. You can watch it casually or go in for huge story arcs, it has both.
In short, bad Star Trek is far, far worse than bad Star Wars, but good Star Trek is miles better than good Star Wars.
