I have one cooler and two cabinets. To be honest I'm not sure why I still keep the cooler considering I own a humidor shop.

But old habits die hard I guess. Basically if you make your coolerdor right its almost as good as a cabinet. But realistically there is nothing as good for aging cigars as a cabinet. I really think it has to do with the amount of wood its lined with. I have a cooler that is entirely lined with wood but my cigars still taste better our of my cabinets. They are so much more completely permeated with cedar aroma during the aging process. Does it make a noticeable difference...to me it does. Your mileage may vary.
