Not to Luffy’s level if they struggle to land any attacks on him.
Not to Gear 5's level. You need to stop saying Luffy as a whole.
Its shit because Luffy comes out of two encounters with Kizaru where Kizaru, the fastest man in the verse, can’t land anything on G5 Luffy and his only method of winning is waiting for G5 to wear off.
Again. Luffy as a top tier
before G5 existed, is resorting to using a hyper overdrive time limited form after being waived off otherwise. And he can
barely land a hit during its entire run. He can barely separate himself from the man, looking at their round 1, G5 vs Kizaru felt like a relatively even battle with an edge to Luffy thanks to WSG at the end. This is really bad considering he looked useless outside of it.
It gets even worse when you factor in Kizaru likely wasn't even close to going as hard as Luffy was. Luffy was willing to turn himself into a raisin to keep up and all he had to show for it was a single attack with superficial damage and getting fed by his enemy. Kizaru may have 2 gears more to climb (1 being fighting serious, 2 being a potential awakening).
