People think Patron is decent simply because that is what the marketing ploy wants them to think. Add a medium price to it and tweenagers think they are getting the good shit. (Usually the same people that think that the vodka in the skull bottle is "awesome" too).
After you get out of the $40-$60 price range, the differences in tequila are so subtle you can't even taste them, let alone appreciate them unless you drink it 100% straight, slightly chilled (no ice). Once you start diluting it with water or other crap, you might as well be drinking Ho-Ho-MessyCo brand of tequila.
I received a couple of bottles of Gran Centenario gran reserva anejo a few years ago from one of our vendors. These go for about $200-$450 per bottle. Taste? Ehh. Nothing to brag about. Went through one bottle and ended up doing cinnamon marg shots with the last half of the bottle. The other bottle is simply setting on my bar now unopened for no other reason that the bottle looks really cool.
