#3 The Undertaker vs. Edge - Summerslam 2008
Even at the height of the John Cena/PG era, the WWE could still put together a strong, captivating feud or two. One such example from 2008 was Edge vs The Undertaker. They'd just capped off a very impressive Wrestlemania 24 show and were now meeting in the main event of Summerslam inside Hell in a Cell.
This was a really entertaining match that deserves its place in our top three. It felt very much like an old school HIAC affair, with just the right amount of weapons and TLC equipment to make it work.
On his day, Edge was one of the best sellers the company had and despite Undertaker never really needing anyone to make him look good, the two complemented each other perfectly and just gave off so much chemistry from start to finish. The ending with Edge being chokeslammed through the mat and the sight of flames bursting out will also live on for quite some time.
#2 CM Punk vs. Jeff Hardy - Summerslam 2009
It's been said before and it'll be said again, the rivalry between CM Punk and Jeff Hardy from 2009 was the greatest piece of business to come out of the PG era. Not only did we see an MITB cash in, a much needed CM Punk heel turn and the eventual suspension of Jeff Hardy, but the two also had brilliant matches in between all the drama as well.
The best of the bunch came at Summerslam 2009 in this fantastic TLC match. We all remember the Swanton Bomb onto the announce table towards the end of the match, and the desperate clawing from both men to try and reach the top of the ladder and retrieve the belt.
All throughout you could just feel the real life animosity between these two, which always makes pro wrestling that much more entertaining. Punk came away with the win here and immediately jumped into his next feud with The Undertaker after a surprise return from the Phenom after the match had ended.
#1 Bret Hart vs. The British Bulldog - Summerslam 1992
Whenever Summerslam season comes around, you'll no doubt get used to seeing various fan-made lists of the greatest matches, moments and main events in the show's history. And there's a very good reason why Bret Hart vs. The British Bulldog normally tops them all. Perhaps you need to be of a certain age to be able to appreciate this one fully, but even the youngest WWE fan in 2017 can recognize brilliance when they see it.
Even when you strip away all of the layers to do with the Hart family feud and the fact that Bulldog was being celebrated by nearly 80,000 of his fellow Brits, this match was a technical masterpiece that will live on through the ages.
This was without a doubt Bulldog's greatest moment and when it comes to Bret Hart and having entertaining matches, what more can we really say? When you think back to all the great Summerslam shows over the years, this one always springs to mind more than any other.
