Bro GV Roger and Garp were buns compared to their prime selves, hilariously they ended up looking even worse than Whitebeard who came out unscathed after a serious clash with DR Xebec lmao.
Regardless of whether 1026 Luffy just learned ACoC, he was portrayed as a Yonko level individual and stronger than even Big Mom.
There is absolutely no reason for me to place GV Roger and Garp that high. Incapable of sky-splitting, no evidence of FS, no-touching CoC from Roger... These guys were Admiral level alongside people like Ryokugyu. I wouldn't even put them above Kizaru.
If there were no sky splits on GV then y'all could've had a point, but the fact that Roger and Garp couldn't sky-split at all against Xebec kills any argument whatsoever about these guys being close in strength to their prime selves. It's over.
