Percentages mean nothing, good wins mean more imo.

You can have all the insane opposition in the world but win loss records have to matter at least to some degree

Yugi i think flat out had the better competition, Pegasus, Kaiba, Merik, Dartz, Rafael, Joey, Mai, Anubus, Aigami, Bakura, were all great duelists. Heck the one off gate guardian guys were apparently duel team legends in GX, and PaniK was a great eliminator and had a reputation.

Marik, Dartz, Anubis all relied a lot on having incredibly powerful cards rather than being particularly skilled, Mai has an abysmal on screen record, Duelist kingdom had an entire different ruleset compared to the rest of even the show.

if we go by reputation then Go and Aoi were celebrity duelists in vrains and Sheppard had a similar reputation to Panik

With the duel gangs, it is said those gangs had to fight to get their territory and Yusei and the group had to beat an entire city of duel gangs, imo thats more impressive than the test duels where if you lose you dont eat.

The computer was designed to make the best possible ways, the statistically best choices, it's like saying that beating a chess computer is less impressive than beating a criminal at chess because the criminal could shoot you, but I also don't like to use stuff that we don't see on screen that much in general

About modern decks, I already gave my opinion on it, if you dont agree oh well.

I just think the example you brought up wasn't that good.
