Short answer: the Marshall Middleton II, if you are buying new. The Vifa Oslo ranks higher than it (#8 vs #31 of 120 large speakers, 4.5/5 vs 4.1/5) but is discontinued, so only consider it used; the Marshall Middleton II is still sold new at $279.99.
The Vifa Oslo is the better-sounding pick. A premium wool covered portable with full, natural, highly accurate sound and rich bass, now discontinued but worth buying used. It supports aptX Bluetooth, which the Marshall Middleton II lacks. The tradeoff: Dip at 270Hz.
The Marshall Middleton II is the deeper-bass, longer-running option. A waterproof stereo speaker with very deep bass for its size, a long battery, a power bank and an app EQ. Its bass reaches about 38Hz before falling 10dB, against 50Hz for the Vifa Oslo. It is rated for 30 hours of battery against 8 for the Vifa Oslo. At 4 lbs (1.8 kg) it weighs noticeably less than the Vifa Oslo at 5.3 lbs (2.4 kg). The catch: Bass boosted which drowns out the midrange.
Buy the Marshall Middleton II new; the Vifa Oslo is no longer sold new, so it only makes sense as a used find.
There is a real gap in water resistance: the Marshall Middleton II at IP67 (brief submersion) against the Vifa Oslo, which has no water resistance.
