Since there's a lot of sugar/lime in the margarita, I wouldn't go with the really good stuff because the subtleties get lost in the mix. A good Sauza tequila like Hornitos, or Commemorativo (although it's price has doubled in the past 5 years, would work just fine. Sauza's Tres Generacions has really gone up in price and I believe it is their top end.

Of course if you don't mind dropping $50 on the Patron for Margaritas, you probably won't ever have a smoother one - especially if you like them strong.

Thanks! I've used the Hornitos and love it. I've never tried sipping though. I'll try Patron. Is there something you eat when sipping to enhance taste (like wine with various cheeses/fruits)?
