Pretime skip luffy had draw back for g2 and g3 but post time skip it was shown that he doesn't have it anymore (fluffy had g4 at the start of post time skip), so do you think fluffy still has drawback from g4 since he unlocked a new devil fruit power up.
From a writer's perspective it makes no sense for fluffy to still have drawbacks from using g4 because if he does, the readers would question why fluffy did not use g5 instead of g4 if it has drawbacks.
