Unfortunately, there are so many variables that depend upon you.The 10 dolla' Tequila with the worm was my last (and worst ever) Tequila experience, but that was 50 years ago...so now interested in the good 12 dolla' stuff with no worm!
(Actually, I know great Tequila is way more than $12!!!)
Buy as small a bottle as practical so you can try lots of different ones (or by the shot at a bar) to find out which you like best. I prefer whites vs reposado vs anejo.
For my list;
Inexpensive - Espolon
mid level - Ocha Plata
premium - Casa Dragones
