Vacuum palm is overrated. Sakura and tsunade's punches had more power and crater creation in them. If that amount of power is inserted in the shockwave she creates, the result would be devastating, hinata's vacuum palm would be out of commision.
I agree on the name. The shockwave makes it reminiscent of 80 palm fists. It could be based off of Kaguya's jutsu it completely decimated the incoming solid mass. A punch would've just cracked it but the shockwave conpletely obliterated it, its on another level.
