Luffy dying actually consumed Gear 5 much more energy lmao. No. Sanji fell unconscious because he used overspeed to the point he collapsed. It's never stated Sanji collapsed because he had been fighting non stop lol. Sanji had to be going all out against Queen who was a neg diff against no haki Big Mom.
Sanji collapsed from exhaustion. That’s why he literally gets up shortly after and proceeds to lead the courtesans to safety and only treated for minor injuries
