The last 2 major villain arcs Luffy has fought (Katakuri and Kaido), he needed to unlock the battle with a "key". For Katakuri the "key" was Future Sight.
Luffy in base seemed useless against Katakuri.
But as soon as he unlocked FS he became somewhat competitive.
Same deal with Kaido. It seemed he wasn't doing much
But with advanced CoC the "key", he became competitive in base
But these differences are exaggerated by the fact because Luffy without the "key" seems useless. But that's an opponent-specific thing.
You take someone like Law. He didn't get any Future Sight, advanced CoA, or advanced CoC. But with the way his powers work, he could have harmed Kaido or Big Mom much better than Luffy.
Kaido even states that Law's powers throw him off. But was Law > pre-CoC Luffy? NO. But Law already had a "key". Luffy was always physically strong, but unlike Law he wasn't very versatile. So some opponents make him look useless based on their own powers.
Luffy gaining Future Sight made him look like he jumped 10x in power. Same thing for him gaining aCoC for Kaido. But these just look this way because he seemed useless before due to him lacking that "key", that even a weaker person, like Law might have. He wouldn't look that useless, against say an Admiral, who didn't have insane skin.
