Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Xiaomi Sound Party ranks #19 of 144 medium speakers by sound quality at $133.62; the Marshall Middleton II ranks #31 of 82 large speakers by sound quality at $330.
What the Xiaomi Sound Party does well: An unusually versatile 1.2kg outdoor speaker: IP67 dust/water protection, USB-C power-bank output, NFC pairing, lights, stereo pairing and a claimed 26-hour battery life. The catch: The sound evidence is mixed rather than universally glowing.
The case for the Marshall Middleton II: Very deep bass for the size/weight. The catch: Bass boosted which drowns out the midrange.
Buy the Xiaomi Sound Party at $133.62 if you want a medium speaker. Buy the Marshall Middleton II at $330 if you want a large speaker instead.

The Two Speakers In Full
Xiaomi Sound Party: $133.62 AliExpress eBay
Pros: An unusually versatile 1.2kg outdoor speaker: IP67 dust/water protection, USB-C power-bank output, NFC pairing, lights, stereo pairing and a claimed 26-hour battery life. Several independent reviews describe a warm, generally balanced sound with clear vocals and useful bass impact when Bass Boost is off. It is also easy to carry thanks to the retractable handle. Measured bass extension of 54Hz (-10dB).
Cons: The sound evidence is mixed rather than universally glowing. One lab review found it loud but flat and unclean with blurred treble, while others hear the Bass Boost mode as boomy upper bass that can bottom out at high volume. It is not the strongest choice for a large party: tested output is around 94dB and rivals such as the Soundcore Boom 2 play louder with deeper bass. SBC is the only Bluetooth codec and there is no aux input.

Marshall Middleton II: $330 Amazon eBay
Older model: the Marshall Middleton (rated 4/5).
Pros: Very deep bass for the size/weight. Measured bass extension of 38Hz (-10dB).
Cons: Bass boosted which drowns out the midrange. Dip around 200Hz, peak at 1kHz, dipped at 1.6kHz. Strange frequency response through the mids.
