Gen G compared to AL, BLG and JDG

Hello,

This years, i didn't had time to follow anything about the LPL like i usually do atleast for top team. But i've been following all match of gen g and other team of the lck.

Today i went to see the scoreboard of LPL, and i was really happy to see AL being the top team of the region. I was also surprised to see that LNG is first place of their group ?

So i'm not sure exactly how it worked because it look like all strong team are together in S group ?

Anyway i was curious : for thoses that did follow the lpl and lck regulary how would you rate AL, BLG and JDG compared to GEN G?
