I think you just have to look at the pirates from the return to sabondy arc to see why HH is such an affective technique, both tactically and for intimidation. The pirates who allied themselves to the fake strawhats were just about to enter NW, and compared to the Monster Trio, they are just cannonfodder. If they had gotten to NW, even their captains would never have become anything more than a Yonko's errand boy. I'm not saying they wouldn't have gotten stronger in NW, they probably would have received some form of offical training somewhere in a Yonko crew, against someone like DD or Shanks, they were ever going to have the power, or perhaps more importantly, the ambition to match the bigger fish. So, HH users can severely diminish their opponents numbers, and make themselves look seriously badass, marching onto and enemy ship and knocking half his men out just by standing there sends a clear message, after all.
