There are plenty of other SummerSlam matches I love. Warrior/Savage is one of them along with Taker/Hart, Angle/Mysterio, Benoit/RVD, Rock/Brock, Hart Foundation/Brain Busters, Hart Foundation/Demolition, Hardy/Punk, etc.
@Ruiner87 Randy Orton's best match ever right there; also, my MOTY for 2007.
Best SummerSlam matches? Bret Hart vs. Dave Boy Smith (1992), TLC I (2000), Kurt Angle vs. Steve Austin (2001), Shawn Michaels vs. Triple H (2002), and Kurt Angle vs. Brock Lesnar (2003).
There have been other fantastic matches in SummerSlam history but those matches are the ones. I'm not fond of Bret/Perfect from SummerSlam 1991. It's a good match and THE moment for Bret Hart, but their KOTR match--two years later--puts it to shame. Can't blame it though. THIS (KOTR) was Perfect at his best, while SummerSlam 1991 saw Perfect at his crippled best.
Punk/Cena from Summerslam was a better match than MITB imo. It was almost perfect apart from the end but even that I didn't have a problem with. The crowd was great (not as good as MITB of course) and the match they worked was amazing. That was my WWE MOTY last year, I had it rated at ****3/4.
Last time I watched the HHH/Foley street fight I didn't think it was as good as I remembered, but still really good obviously. I personally prefer HHH/Shwan from Summerslam 02 I think.
I like a lot of Triple H matches, but his absolute best performances have to be Fully Loaded against Chris Jericho and Vengeance against Batista. Thinking about it, the performance he put at last year's WrestleMania is right up there as well. I'm just talking of performances here.
On the same topic, I really ADORE this match between Hunter and Jeff from No Mercy 2008.
