Short answer: the Onn Large Party gen 2 for the longer battery and karaoke inputs. The Rockville Rock Party 6 is a simple 6.5-inch woofer speaker with a claimed 6-hour battery and no app or EQ, with bass limited to around 60Hz. The Onn gen 2 doubles that to a 12-hour battery and adds karaoke mic and guitar inputs plus wheels, though Consumer Reports found its own bass boomy and treble smeared.
