Okay, these aren't exactly comparable but here be the deals - Bulleit Bourbon @ $16 vs. KC1B @ $27.
I've already bought 2 of the first and 3 of the latter. I've had a couple pours of the Bulleit, which I like and find represents the Four Roses style very well. I believe it's fine everyday bourbon.
I don't care for Beam Black and haven't tried much else in the Beam line so far (only the Kirkland small batch, which I found good). Yet, most reviews of KC1B are good to great with the only reservation involving price.
So, which shelf (if either) would you clear?
