Short answer: the Marshall Middleton II. It ranks #31 of 120 large speakers by sound quality, rated 4.1/5, at $279.99; the B&O Beosound Level ranks #92, rated 2.8/5, and costs $2,250, which makes this an easy call rather than a real tradeoff.
The Marshall Middleton II is the better-sounding, deeper-bass choice. 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 60Hz for the B&O Beosound Level. It is rated for 30 hours of battery against 16 for the B&O Beosound Level. At 4 lbs (1.8 kg) it weighs much less than the B&O Beosound Level at 7.3 lbs (3.3 kg). Watch for: Bass boosted which drowns out the midrange.
The case for the B&O Beosound Level: A sculptural luxury speaker that works on battery or mains, mounts on a wall, and streams over Wi-Fi with upgradeable modules. The tradeoff: Not very deep bass, peaks in midrange.
Buy the Marshall Middleton II. It is rated higher for sound quality than the B&O Beosound Level and costs less, so only choose the other one for a particular feature it does better.
If water resistance matters to you, the Marshall Middleton II at IP67 (brief submersion) holds up far better than the B&O Beosound Level at IP54 (splashing).
