Short answer: the Tower Max, unless price or size decides it for you. The Max adds three 11-inch woofers, 2,150W specified output, 10-band EQ and 360-degree sound, and AudioTribe measured 110.6dBC at about 6m outdoors with strength from 40-100Hz. The Tower 10 is the older AC-powered model, and its review notes flag bass reduction at higher levels as a core limitation.
Tower Max is the new venue-scale Sony flagship; Tower 10 is the older AC-powered large model. Max adds three 11-inch woofers, 2,150W specified output, 10-band EQ, 360-degree sound and XLR/RCA/USB-C connections.
Choose the Tower Max for deeper system capability: AudioTribe measured 110.6dBC at about 6m outdoors and found the Max especially strong from 40-100Hz. It is very heavy at 124.1 lbs (56.3 kg).
Choose the Tower 10 only when its lower price or smaller cabinet is decisive: Its current review notes identify bass reduction at higher levels as a core limitation for a large party speaker.
Buy the Sony ULT Tower Max. It is rated higher for sound quality, and saving $203.66 with the Sony ULT Tower 10 does not make up for the sound-quality gap.
