Everyone loves Lightning Rounds, but how bout something with a bit of a twist to them. Best matches for people who weren't having them or having them with only a select group of talent (a.k.a Shawn or Bret)....
Davey Boy Smith - Singles Match, Post-Bulldogs Era, Not vs. Shawn, Bret, or Owen
That's pretty specific. Probably I'd say one of the Hennig matches on Coliseum video.
Andre The Giant - Heel run of 1987 and later.
 
Against Bret in Milan?
Brutus Beefcake - Singles Only. I won't be cruel enough to say "WCW Only".
 
The Dream Team blowoff against Valentine was good, and I recall him having a really good one against Savage in late 89.
The Undertaker - Pre-Attitude Era, Not vs. Mick Foley, Shawn, or Bret.
 
I'm gonna say Warrior because they were decent enough.
And how bout some not-so-good's for the hell of it with the obvious choices of "great" workers:
Worst Bret Hart Match
Any of his shitty Dino Bravo abominations on Coliseum video.
Worst Shawn Michaels Match
He had some bad ones on TV in 97 when he was high all the time.
Worst Ric Flair Match
JY motherfuckin' D in 1990.
