#2 AJ Styles vs. Samoa Joe (SummerSlam):
This was the match that AJ Styles, Samoa Joe, SummerSlam, and the WWE Championship needed. It was the best in all four categories this year, and despite a screwy finish, it somehow managed to not make you feel disappointed beyond that singular moment because it escalated the feud and the story being told by both men.
For the first time in a while, AJ Styles looked like a fighting, aggrieved champion to get behind instead of a filler one. Samoa Joe looked positively vicious and ruthless, and who can forget "I'll be your new daddy!?"

This match sent the feud over the top into the main roster's best program of 2018, and if NXT wasn't having such an unbelievable year, it would likely be set in stone as one of WWE's top 10 matches this year.
