I evidently have read the chapter, sir. Otherwise I wouldn't have used scans from said chapter, would I? I'm impressed by your lack of comprehension, it's astounding considering you're literate.
The fact Luffy needed to fight a heavily injured Doflamingo, on the verge of death, with the assistance of Law and all the gladiators proves that Doflamingo is stronger than Luffy regardless of what gear he is using. All damage he received considered, Doflamingo was able to inflict damage on Luffy and counterattack Luffy's relentless barrage whilst he was using Gear 4th, which proves that even in the state he was in, he wasn't far below Luffy. Thus anyone with common sense can conclude (especially after the portrayal in todays chapter) that Doflamingo beats Gear 4 Luffy whom is in turn slightly stronger than Doflamingo on the verge of death.
Note: Fully healthy Doffy could use his awakening to a much greater extent, most likely. His awakening had Luffy on the ropes.
