Short answer: the Yeahbox Sonic Boom Max 3 on paper, the JBL Partybox On the Go for tested basics. The Sonic Boom Max 3 claims 200W RMS (300W peak) from a true 3-way, 5-driver array, but those specs are manufacturer claims from a budget brand with limited independent testing. The On the Go ranks #67 of 113 against #59 of 113, includes a wireless microphone, and has a poor water rating at $329.95 against $228.99.
Buy the Yeahbox Sonic Boom Max 3. It is rated higher for sound quality than the JBL Partybox On the Go and costs less, which makes it the one to get unless you need something the other one does better.
