Eh...it's SW juice which has historically been very good even at extreme age. Plus bourbon and added Pappy hype.
IMO for all whiskey 15-21 years is the sweet spot.

It's definitely a flavor some people like. I always wonder what it would be like to taste things like a different person for a day. A buddy of mine loves the 23 elijah craig, and some of the older orphan barrel stuff. To me even the 18 just taste like a ton of oak and nothing else. My sweet spot for bourbon has always been in the 9-15 range (exceptions made for some years of the GTS and ER17), while single malt I match up with you on that.
ETA: I will say that I like Japanese whiskies older than just about any other. I'm guessing it's the climate and elevation they age a lot of them at, but they seem to take being extra aged very well.
