I'm not familiar enough with 80s Lucha to declare this #1 without seeing the other 93 matches first, but this is going to be way up there. The 2/3 falls format finally works for me with this match. The post match really seals the deal, with MS-1 displaying a bit of integrity and having his head shaved while on his knees with hands behind his back.
I don't speak hardly a word of Spanish, but did the announcers mention something about cigarette-smoking lady being Sangre Chicana's madre?
