Well, I know that if I could only drink one bourbon, I'd drink PVW 20. However, that's expensive and rare. So with the advice of this site and others, I've been sampling $20-30 bourbons. In the past few months, I've tried (in no particular order) OGD BiB, Rittenhouse BiB, 4 Roses SmB, EC 12, and EWSB. I can say that they have all been good and I'd be happy to drink any of them, but here is my order of preference:

4RSmB
EC12
EWSB
Rittenhouse
OGD BiB


There is something about the 4R Small Batch that is just perfect for me. There is just the right amount of citrus, spice and smoothness. I actually prefer it to many more expensive bourbons like 4RSB (or even Willett's 3 yr old rye).

Now, of course, this doesn't mean I would be opposed to seeing if there is something better (like AA10)
