Its all a personal preference. Its called the line of diminishing return and its different for everyone.
You find it with all fine things:whiskey, watches, knives, Guns, ETC
There is a point were the amount of performance you get in something costs exponentially more. for instance a bottle of blantons bourbon is smoother than makers and only double the price, however a bottle of pappys is only a bit smoother and 5 times the price. To some people that not worth it. To me and many others it is. When you put alot of time and personal attention into things that is where the cost somes from, and while the return may be paltry to some it makes all the differenc ein the world to others myself included.
we have a winner

Any alcohol will get you drunk at the end but I prefer a smooth one; same for knives
