Short answer: the Marshall Middleton II. It ranks #31 of 115 large speakers by sound quality, rated 4.1/5, at $279.99; the Devialet Mania ranks #52, rated 3.6/5, and costs $899, so there is little reason to consider the other one.
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 47Hz for the Devialet Mania. It is rated for 30 hours of battery against 10 for the Devialet Mania. At 4 lbs (1.8 kg) it weighs noticeably less than the Devialet Mania at 5.1 lbs (2.3 kg). The catch: Bass boosted which drowns out the midrange.
Why pick the Devialet Mania: A compact, good looking Wi-Fi and Bluetooth stereo speaker with Alexa built in and splash resistance. The catch: Not very loud.
Buy the Marshall Middleton II. It is rated higher for sound quality than the Devialet Mania and costs less, which makes it the one to get unless you need something the other one does better.
If water resistance matters to you, the Marshall Middleton II at IP67 (brief submersion) holds up far better than the Devialet Mania at IPX4 (splashing).
