It's hard and I wish this was a top ten, but there'd be a top 5 out of that, lol.
I'll still list briefly the last 5 in my top ten, but I have to choose a Top 5 so here we go:
Hell in a Cell
Edge vs The Undertaker (not only a nice HIAC bout which we dont see anymore and may have been the last great one, but did you see the fucking ending?!! lol It's hard to outdo HIAC even for my number 2 match when this one features what that one has!)
TLC Match
(WWE Tag Team Championships)
Edge & Christian vs The Hardy Boyz vs The Dudley Boyz (there's too much great about this match lol it has to take the number one spot, yes over some personal matches, rare matches, but this one epic! it really had pure excitement from start to finish, pure wrestling classic? no, one of the best matches in SS history? yes! As you'll see from my list, SummerSlam has a love fetish with ladder matches, great ladder matches, and some of the very best were at this event, but the added element of tables and chairs, and not just for the fact of the aforementioned triple tango of weapons, but the usage of these weapons, made this one of the greatest matches at the event! These matches you're basically watching a split screen with a replay the whole time FOR A REASON, am I a little over-awed, maybe... maybe not)
Steel Cage Match
(WWE Championship)
Bret Hart vs Owen Hart (a bitter rivalry between two brothers made it all the more better, but what really made this match is the fact that there's a Steel Cage around the ring, with less use of it as a weapon, yet usage in a very special rare manner that adds to the match in a very different way, gotta give them credit for having the suspense factor without weapon usage much, it was used, but not like you usually see it done moreso throughout the entire bout)
I Quit Match
Ric Flair vs Mick Foley w/Melina (this match was pure awesomeness, it had a nice ending that you really didnt think was gonna happen, though the way it happen didnt make the loser look bad and it was a brutal bout, Flair's snapped before, but this was special)
Singles Match
(WWE Intercontinental Championship)
Bret Hart vs The British Bulldog (best pure wrestling match in the history of SummerSlam)
(6-10 of my top ten)
Ladder Match
(WWE Intercontinental Championship)
The Rock vs Triple H (I loved HBK/Razor's but I liked this one better, the spots was better, it was more heated, People's Elbow in the ladder! yay and the catching HHH off the ladder into a Rock Bottom)
Elimination Chamber Match
(World Heavyweight Championship)
Triple H vs Chris Jericho vs Goldberg vs Randy Orton vs Kevin Nash vs Shawn Michaels (I love Elimination Chamber Matches, but I cant put this in my top 5 though the nice wrestling at the start between Y2J & HBK made it great and the slick ending by HHH, other matches were just better)
Unsanctioned Street Fight
Shawn Michaels vs Triple H (oh damn this was great, HBK's first match back and even after it was over, the last vile act by The Game, epic stuff, I was wondering if he could still go, was happy to see my first live HBK match [on TV]
Ladder Match
(WWE Intercontinental Championship)
Shawn Michaels vs Razor Ramon
Ladder Match
(Custody of Dominick)
Eddie Guerrero vs Rey Mysterio (it was personal, there was a child involved, there was a friendship deteriorated, there was mental hurt and pain and the match reflected all of that and Vickie getting involved was a nice touch, Eddie and Rey's best storylines I believe and the match as always, awesome)
that's my TOP TEN overall [above] and you can of course see the Top 5 since I had to put them in order
HONRABLE MENTIONS:
Singles Match
(Icon vs Icon)
Hulk Hogan vs Shawn Michaels (I loved this match for Shawn's overselling, it was the best overselling of all time! epic showdown, entertaining match)
Singles Match
(Neither Man Permitted to hit the Other in the Face)
Shawn Michaels vs Rick Martel (I thought the stip was very very cool, especially with the two men in the ring, it made sense, and the match was very well done too, I enjoyed this)
Singles Match
(WWE Championship)
Randy Savage vs The Ultimate Warrior
Singles Match
(WWE Championship)
Stone Cold Steve Austin vs Kurt Angle
Triple Threat Match
(WWE Championship)
The Rock vs Kurt Angle vs Triple H

Kiss My Ass Match
The Rock vs Mr. Ass
TLC Match
(World Heavyweight Championship)
Jeff Hardy vs CM Punk
Singles Match
(WWE Championship)
Kurt Angle vs Brock Lesnar
Falls Count Anywhere Match
Shane McMahon vs Eric Bischoff (it got personal, it had a nice Dive by Shane, hell it was fun to watch, he didnt get Vince in the ring (unfortunately we didnt get to see that) but he got Shane
Till Death Do Us Part Match
(Winner Marries Lita)
Kane vs Matt Hardy (not one of the best matches, but the stip made me give this a shoutout, it was awesome)
Singles Match
Edge vs Matt Hardy (couldnt have it in my top, it was great, personal, but HBK vs HHH was miles better to me as a match, even though it wasnt a true issue like Hardy/Edge, the match was awesome as a match with no rules aside from it being Shawn's first one back)
Singles Match
(ECW Championship)
John Morrison vs CM Punk (this match really saw two young guys start a rivalry that would show they are the future out of the wake of the biggest wrestling tragedy ever (yeah it is, two others were killed even if you dont like Benoit, or care that he killed himself)
Singles Match
(WWE Championship)
The Rock vs Brock Lesnar
Singles Match
Kurt Angle vs Rey Mysterio
Singles Match
Chris Jericho vs Ric Flair (this match had pure aggression and intensity in it. You had to love every minute of it)
Singles Match
(WWE Intercontinental Championship)
Bret Hart vs Mr. Perfect
Singles Match
Hulk Hogan vs Randy Orton
Singles Match
The Undertaker vs The Undertaker (wasnt great of a match, but the thing of the real vs fake, i just liked it)
and I believe this Sunday,
Singles Match
(WWE Undisputed Champion)
John Cena vs CM Punk
Special Guest Referee: Triple H
could be on the list after what should be an epic showdown, but again I must say, it's very hard to choose and years go by and you may forget a few wow matches you've seen, but go back and it's really hard to pick!
I had to atleast shout out the ones that didnt make my Top 5 and Top 10 overall.
