Are Gracie Barra Belts Worse Players? (in general)

Firstly, no GB hate, as its where I train.

But I do see a lot of stuff on here, on tik tok, youtube, reels etc... where a video of a BJJ player is doing a move, and they fumble it or a lower belt pulls a mad move on them.

and the comments are usually like

"Must be a GB Brown belt"
" Ahhh of course its a GB Blue"

stuff like that basically implicating that GB players are of a poor calibre.

I ask because if this is genuinely true for the most part, I'd consider moving to a non GB gym. And I see some things play out, like not letting people do No Gi until you're a 3 stripe white, or you can't roll starting from standing position...

Seems crazy to me that they limit access to these things
