I was thinking of purchasing some of Gushiken's fights but I know very little about him and don't know where to start so any input on which of his fights were entertaining or masterful.
Gushiken had barely any back-and-forth competitive title fights, the most you will get to that are his last two against Flores, by which point he was claiming serious trouble making weight and being burned out. not good fights to see him at his best in, regardless of the truth of his excuses or not. Majority of his other title fights are either one-sided beatdowns of mediocre to serviceable fighters, or comfortable going through the motions lopsided decisions(forget the nonsense splits he got against Rios and Marcano). The two exceptions that stand out to me, are the Aniceto vargas fight, which is a truly awful fight where gushiken does next to nothing and looks bad against an overmatched cautious foe, before getting a horrible brutal stoppage late on....and the Alfonso Lopez fight, where Lopez regained a lot of his earlier peak sharpness and gave a great effort before being stopped. Martin Vargas is probably his best dominant performance against a good opponent.Vargas made Canto look a bit feeble at times, but Gushiken impaled him on the end of his straight punches all fight.
I think most Gushiken fights are good to watch, but they are more technical/tactical affaris. But the Lopez fight is good IMO
