You must be kidding about Lee Sedol.

Yes, he is not as dominating as before. (is it because he is weaker or
because the other ones got better?)
But he is still #3 in Korea having only dropped there this month,
being #2 for most of the last year. (btw overtaken by Park Younghoon,
who is not really a younger generation)
In Korea usually the Myeongin and Kuksu are considered the most
important titles. He owns one currently, dropped out in Semifinal in
the other one. Looking at the last big global title(MLily Cup), he
lost 2-3 in the final.

Not sure what you are asking for, but in pretty much any metric, only
Park Junghwan can currently be considered stronger in Korea, and less
than a handful players can be considered even with Lee Sedol.
And even worldwide... Yes, there is Ke Jie. Who else? Again you won't
find more than a handful Chinese players. And the performance of
Japanese/Taiwanese players on international level can easily be
ignored.

So in the end, we have 2 candidates, who may be strength wise a better
choice than Lee Sedol.
But then there is of course name value, legacy etc. Lee Sedol
represented and dominated the Go scene for more than a decade. And
neither Ke Jie nor Park Junghwan come even close to that, even with
their great performances in the last 1-3 years. There is a reason why
people asked for a Jubango involving Lee Sedol, and neither of the new
"kids".

So he was by far the biggest fish Google could ever catch for that
game, for Go insiders as well as for people outside the Go scene.
