Notice in the spoiler text of the actual manga they used ZERO of those excuses as to why it should be unimpressive, they did however directly say it was impressive that Sanji didn't use CoA, please tone your agenda down a bit, they wanked the reaction to this feat in this chapter, so we as readers of the chapter and not disciples of headcanon, should follow what the manga thinks is impressive.
Queen is more diverse in combat methods, more durable and physically stronger than Killer, Hawkins isn't even given Tobi Roppo status, but if he was he'd be at most Drake level, who was portrayed slightly lower than Whos who/Sasaki, then you have a gap till Jack, and then you have a bigger gap until King/Queen.
