Short answer: the Soundboks 4 for loudness, the Electrotec Stage One for sound quality and runtime. The Soundboks is tied for loudest battery-powered speaker and has a removable 40-hour battery, but it is very large, not stereo and trails the top Partyboxes on neutrality and bass. The Stage One is balanced with a dual swappable battery good for 100+ hours, though it costs $251 more and is tuned for loudness over deep bass too.
Buy the Electrotec Stage One. It is rated higher for sound quality, and the $251 you would save on the Soundboks 4 does not close the gap.
