Nakamura v. Zayn is probably my MOTY at this point but DIY v. The Revival is right up there.
The others that come to mind are:
Omega v. Naito (G1)
Styles v. Nakamura
Kushia v. O'Reilly
Okada v. Tanahashi (Wrestlekingdom)
Also, I never thought I'd say this, but Roman Reigns is on my short-list (v. AJ Styles). They had an awesome match at ... Extreme Rules maybe?
I'm betting Okada v. Tanahashi wins the most MOTY awards around the web, partially because of the great storytelling. The loser being so crushed that they break down and cry afterwards is how you show how much your World Title means.
Moment of the year goes to Taichi's valet for losing her top in the ring and not being able to get it back on (kind of SFW because you can't see anything at all).
