The resident "expert" at my (new) local Total Wine & More, recommended Don Sergio Anejo ($23) as equal to the Patron Anejo and a bit better than some other equal priced competitors, like the Gran Centenario. I don't have anything to compare it to side by side, and my memory of the Patron is several years old.
I think the longer aging of the Anejos can sometimes make them taste more similar to other aged distilled spirits and less like Tequila. As I do further research, I may find that for me, the Reposados could be the ideal middle ground and might serve double duty for both sipping and Maragaritas.
