Short answer: the Onn Large Party gen 2 on price, the Audiocase S5 for its battery and claimed output. The S5 pairs dual 5-inch woofers with a removable battery rated for 30 hours and up to 108dB output, though there is no app or EQ to adjust its sound. The Onn costs a fraction of the price with its own karaoke mic and guitar inputs and wheels, though Consumer Reports found its bass boomy and treble smeared with no app or EQ either.
