I had the aquadiente once, it was very smooth but I didnt drink enough to get a good judgement on it. My normal liquor store doesnt carry it but now that you've reminded me I'll have to go pick some up.

Tequila is good and great as long as its an anejo or reposado, really anything that you can sip on straight and not have to mix into a margarita. Clear liquor is always just asking for trouble and terrible hangovers, I'll mix the blanco into a margarita for the girl and sip straight anejo myself, preferably with a cuban cigar.
