Short answer: the Onn Large Party gen 2 for value, the Zealot PT21 for bass and loudness. The Onn has a handle and wheels for easy moving and costs nearly $96.86 less, but it is not quite as loud and not as deep in the bass as the PT21. The PT21’s dual 166mm woofers deliver quite deep bass for the price and it bundles a wireless mic with echo.
Buy the Zealot PT21. It is rated higher for sound quality, and the $96.86 you would save on the Onn Large Party gen 2 does not close the gap.
Battery life favors the Zealot PT21: rated for 60 hours against 12 hours for the Onn Large Party gen 2.
