It's a good bourbon, but I don't think it's a whole lot better than the Jefferson Reserve. The schtick with it being ocean aged is that the movement of the barrel at sea causes the aging process to accelerate, as the bourbon is moving within the barrel due to the boat movement as well as due to the changes in temperature, etc. So a 5 year aging process is supposed to give you more like an 8 year age. Who knows...
I'm always amazed at the prices some people are willing to spend for bourbon, or wine, or whatever. I think the Legent bourbon is excellent at its price point, as is the Knob Creek. If I want a treat, I'll buy the Booker's, but it's at a price point that makes it a special occasion bourbon.
