Wondering the same. Not just for this series, but other FKMT works as well.
You see Kaiji in Akagi come up in "best manga of all time" polls (not in the top 10 or anything, though) that are done from time to time, but I've also read claims that Gin to Kin is FKMT's most well-received work in JP. No idea how true this is, though.
