Short answer: the Marshall Middleton. It ranks #33 of 126 large speakers by sound quality, rated 4.0/5, at $257.52; the Devialet Mania ranks #55, rated 3.6/5, and costs $899, which makes this an easy call rather than a real tradeoff.
The Marshall Middleton is the better-sounding, deeper-bass option. A waterproof stereo speaker with very deep bass for its size, a long battery, a power bank and a detachable strap. Its bass reaches about 39Hz before falling 10dB, against 47Hz for the Devialet Mania. It is rated for 20 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 tradeoff: 5db dip at 1.7kHz and 6.3kHz.
What the Devialet Mania does well: A compact, good looking Wi-Fi and Bluetooth stereo speaker with Alexa built in and splash resistance. Watch for: Not very loud.
Buy the Marshall Middleton. 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.
Water resistance is not close: the Marshall Middleton is rated at IPX7 (brief submersion), well ahead of the Devialet Mania at IPX4 (splashing).
