Short answer: it depends on whether you need a battery. The Sony ULT Tower Max runs only on mains power, while the JBL Partybox 720 has a battery rated for 15 hours. The Sony ULT Tower Max ranks higher on sound quality (#1 vs #6 of 13 large party speakers, 4.8/5 vs 4.7/5). Get the Sony ULT Tower Max if it will always be plugged in, or the JBL Partybox 720 if you want to play away from an outlet.
The Tower Max is the no-compromise AC flagship; the PartyBox 720 is the more manageable JBL alternative. Sony supplies three 11-inch woofers, 10-band EQ, 360-degree sound and RCA/XLR/USB-C connections. The PartyBox 720 is lighter, less expensive, runs up to 15 hours on its battery and uses JBL’s familiar wheeled PartyBox format.
Choose the Tower Max for maximum system scale: It is intended for the largest events and offers the better connection set for a DJ, but its 124.1 lbs (56.3 kg) weight makes it a serious commitment to move.
Choose the PartyBox 720 for a less expensive, more portable large-party speaker: It can play away from an outlet on its battery and is substantially easier to transport.
Buy the JBL Partybox 720 if you need to play away from an outlet. Buy the Sony ULT Tower Max if it will always be plugged in.
