I've only had Jose Cuervo and all I know is I hate everything about the flavor.
even the good stuff has two differnt flavors. if you hold it in you mouth, it tastes sweet. but when you swallow you get that turpentine taste a bit, to a lesser extent with the good stuff
the stuff i was drinking was expensive though, Corzo ($80 a bottle). but there was one that was pretty good and cheaper like 45$ a bottle (calvadores or something). the taste was good but it was a little more harsh after you swallow it
