Go Seigen dominated every top player of his day in the most serious of matches. Also, it is tough to fault someone for not winning tournaments in an era when tournaments were rare. The Meijin tournament began in the 60s and Go Seigen was not the same after his car accident in 1960. The Honinbo Tournament began earlier but my memory is that he did not participate in more than a handful of those because of conflicts with the Nihon Ki-in.

And he beat the snot out of every top player of his day in matches that were matters of honor. Sometimes to the point that they became obsessed with him.

Fujisawa won a lot of tournaments. The lasting image of him is that he was the best when he cared. The Kisei title was like THE de facto world championship during his era. To put it in contemporary terms, it was like an international tournament that attracted every top 40 player in the world with a $2,000,000 prize for the winner. Now suppose that someone won this tournament several years in a row at age 40. On top of that, suppose that this player would drink, smoke, gamble, and party most of the year and quit those vices cold turkey one month before the tournament so that he could prepare. That person would get many votes for being the best in the world.
This was essentially Shuko during his run of six Kisei titles, which began when he was 51 years old. He was no longer considered the best after that ended, which was followed by the Kobayashi-Cho era. Of course, many people still believed that he had the best understanding of go, but that is different from being the best at playing go.
