Short answer: the Vifa Oslo for treble detail and bass, since the Mifa Wildbox is no longer available. The Oslo delivers extreme treble detail with decent bass, though it has a dip at 270Hz. The Wildbox’s neutral midrange response is appealing, but it does not seem to be available anymore.

Buy the Mifa Wildbox or the Vifa Oslo, whichever you find used in better condition; both are discontinued. For a new speaker, start with the JBL Xtreme 5 instead.
There is a real battery-life gap here: the Mifa Wildbox is rated for 24 hours, the Vifa Oslo only 8 hours.
If water resistance matters to you, the Mifa Wildbox at IP67 (brief submersion) holds up far better than the Vifa Oslo at no water resistance.
