There was some crazy tag match from around Fully Loaded 1998 with, I think, Kane/Mankind, Austin/Taker, the Outlaws and Rock and Dlo that really stood out to me at the time.
I would also shorten the parameters of this to pre 2000, as the departure of Russo, the arrival of the Radicals and the ascendency of Edge, Christian, the Hardy's and Angle led to longer matches with less run ins and nonsense. I could easily pick decent TV stuff from 00-01 but really struggle for 98-99 fwiw.
