Imposed my own personal criteria: a 'jam' should be self-contained and not include more than a single song, with the exception of extended quotes, or lyrics/structures sung over jam segments (ie. Meatstick-> Kung could be considered a single jam, But 6/14/00 Twist-> Walk Away would constitute two 'jams').

My ballot ended up being a mixture of classic heavy hitters and some personal dark horse favourites that I think nevertheless deserve their place alongside said hitters in the canon. Oddly enough I saw 7 of the 10.

12/6/97 Tweezer
12/7/99 Halley's Comet
2/28/03 Tweezer
8/17/97 Bathtub Gin
7/6/94 Reba
11/17/97 Ghost
12/30/97 ACDC Bag
12/31/99 Split Open and Melt -> Kung
8/11/98 Runaway Jim
8/15/98 Ambient Jam

Some tough calls: 4/3/98 II, 6/14/00 II, and 11/22/97 II are among my top 10 sets to be sure, but there isn't a single jam that stood out from them to merit inclusion over the above. Honourable mention to 7/2/97 Stash, 8/10/97 Cities, every Harry Hood from 1994 and every Ghost and Bathtub Gin from 1997-2000.
