Short answer: the Marshall Middleton. It ranks #34 of 115 large speakers by sound quality, rated 4.0/5, at $279.99. The Xdobo X8 Max ranks #83, rated 2.9/5, at $105.99, $174 cheaper, which does not close the gap in sound quality.
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 52Hz for the Xdobo X8 Max. It is rated for 20 hours of battery against 15 for the Xdobo X8 Max. At 4 lbs (1.8 kg) it weighs noticeably less than the Xdobo X8 Max at 6.3 lbs (2.86 kg). The tradeoff: 5db dip at 1.7kHz and 6.3kHz.
The case for the Xdobo X8 Max: A feature packed waterproof boombox with a huge battery, power bank output, and enough volume for outdoor background music. Watch for: The voicing is bass-heavy with thin, boosted highs that can turn harsh, and reviews report distortion rather than clean dynamics when pushed hard.
Buy the Marshall Middleton. It is rated higher for sound quality, and saving $174 with the Xdobo X8 Max does not make up for the sound-quality gap.
