Debatable, 100thieves have accomplished just as much as OG.
Also liazzz and gratisfaction are worse then any players in OG.
Valde plays similar style to liazzz and is undisputably the stronger player.
Gratisfaction is happy to put up a 1.0 rating as an awper.
AZR is probably a better IGL then AleksiB and Jkaem is very good too.
I think OG is stronger.
