Short answer: the Marshall Kilburn II. It ranks #36 of 78 large speakers by sound quality at $219; the Devialet Mania ranks #40 and costs $899, so there is little reason to consider the other one.
What the Marshall Kilburn II offers: 20W Class D amp + dual 8W tweeters. 20+ hour battery with quick-charge (20 min charges 3 hours of play). Rugged design with leather handle and reinforced corners, IPX2 rated. Thrives with rock music. Bluetooth 5.0 with 30ft range. Watch for: Boosted upper bass, not very detailed, not as deep bass as competitors, upper mids peak. Very low IPX2 water rating. AC charging
What the Devialet Mania offers: Small, nice looking. Watch for: Not very loud. Extremely high price. Bass boosted. Tweeters are not aimed at you and there’s a huge treble rolloff off-axis as compared to the Beoplay P6 in the comparison video. Only 10 hours of battery. Oluv didn’t like the upper mids or treble (mentioned on his Patreon)
