WLW is infinitely better, IMO, than any of the Pappy offerings. George T Stagg is as well. The Four Roses Small Batch LE is usually better, for my palate, too, and some of their single barrel LEs have been better over the years than anything Pappy has released in ages.
To be fair, though, today's Pappy is different whiskey than what made PVW "famous" in the first place. There's no more whiskey coming out of Stitzel-Weller, and the new pappy barrels aren't aged there either. It's all Buffalo Trace these days (except the 23 year - which may contain some S-W juice still...not sure- which I thought was terrible from the start). Buffalo Trace is good whiskey, but it's not the "same" whiskey by any stretch. Very different flavor profile, and much less unique than the pappy was for a long time.
Ironically, when the Weller craze took off, people said it was the same stuff as Pappy but younger (or the non-choice barrels)...it wasn't...yet. The VW stuff was still a mix of S-W, Lawrenceburg, and others, while the Weller was all Buffalo Trace. Nowadays, it's the same mash from the same distillery as almost all the PVW. 5-6 years ago, it wasn't.
