My top 5 and honorable mention.
The Ankle Lock GOAT Submission with the most impressive list of tappers
The Five Star Frog Splash. There are a lot of top rope finishes that are more impressive and there are many frog splashes but no other aerial finisher sold the idea of a high-risk move as much as the five star frog splash. RVD's choice to sell the impact as the man delivering the move was genius and I used to want him to get another finisher as a kid because of it.
The 619 the greatest unbelievable move in wrestling, a sequence almost never ending the same way but always beginning with knocking his opponent to the 2nd rope and swinging with a kick to the face. Sometimes with unrealistic moves, I think they come down to the performer, there are moves like the Canadian Destroyer, Rebound Closeline that get people tight but some of those same people look forward to seeing the 619 and I feel like that is because of how special Rey Meysterio Jr is.
The Razors Edge. I just love it, probably my favorite powerbomb variation.
Stone Cold Stunner the perfect finisher for the anti hero. The kick to the gut and shooting birds and shytting talking his downed opponent.
If anybody liked what my other choices I'm going to lose them now
My greatest heel finisher is The Pedigree
I pick this because no other heel finisher filled me with as much dread as this and I believe heel finishers should be simple and most modern wrestlers can't help but please the crowd as much as the babyfaces. I hated this move and I didn't even want to see it as a child because I knew when he performed it the match was over.
