Short answer: the JBL Boombox 3 Wifi for loudness, the ZZA K8 as the cheap gamble. The Wifi is the loudest speaker in the category, though its bass is boosted. The K8 is completely insane value for the money, but its very V curve frequency response can be harsh in the treble range.
Buy the JBL Boombox 3 Wifi. It is rated higher for sound quality, and the ZZA K8 is discontinued, so it is only available used.
