Patron vs. Avion vs. Don Julio?

Which do you prefer? I've only had Patron Silver and it was better than bottom shelf tequilas but not worth 2 1/2 times the price in my opinion. Planning on doing a blind taste test sometime in the future but for now I am interested in people's opinions. Patron and Avion seem to be highly media and celebrity promoted but people seem to either love them (bandwagon/advertiser suckers?) or hate them (competition?), while Don Julio rides more on it's reputation as an actually good tequila and seems to get consistently good reviews. Which do you prefer? Thanks! :D
