Being I am a Makers Ambassador #435427 and my barrel is going to be ready in a few years, I'd have to say the Blanton's has a little more depth of flavor, a little sharper start. Is it better? I think the answer is each is different enough to have both on hand. I will mix Makers sometimes...with lemonade, into bbq sauce, with coke even but the Blanton's, always neat or with a couple of ice cubes to open it up, never mixed.
This reminds me, maybe we can get 29 members that enjoy a Makers and get a CVO barrel going, it can be 6 years or more before it is ready.
