Southern Tiers PumpKing is pretty much the only pumpkin beer I enjoy. The rest are just so darn mediocre, IMHO. Even my favorite breweries - Dogfish, Weyerbacher - pretty much FAIL when it comes to pumpkin beers.
That said, I still try just about every pumpkin beer out there, just in case....
So, I recently bought a sixer of Fisherman's Pumpkin Stout. I've been drinking one per night the last five nights, and each night they grow on me a bit. It is a stout, with a very slight "pumpkin beer" after taste to it (read: a hint a holiday spices). I think its actually pretty well done. Of course, this is in part bc my expectations have been lowered to such a ridiculous degree over the past few years of trying every pumpkin beer out there.
