Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The JBL Partybox 720 ranks #6 of 13 large party speakers by sound quality at $1,099.95; the Sony ULT Tower 5 ranks #5 of 53 party speakers by sound quality at $448.

Different sizes. The PartyBox 720 is a 68.3 lbs (31 kg) large party speaker with 800W. The ULT Tower 5 is a 28 lbs (12.7 kg) party speaker with a 9 inch woofer and 300W. Each is rated within its own class.
The ULT Tower 5 is the practical choice. It has a removable battery with a claimed 20 hours, a 10-band EQ with ULT1 and ULT2 bass modes, LDAC and AAC, and balanced XLR, RCA and mic inputs. Early impressions describe deeper bass and clearer sound than the JBL PartyBox Club 120. It has no wheels.
The 720 is for scale. It has wheels, two removable batteries for a claimed 15 hours, guitar and mic inputs, USB-C playback and very high tested output. Expect a dark, bass heavy default tuning that benefits from the app EQ, and uneven sound to the sides.
Both are IPX4 and both link to other speakers with Auracast.
Buy the JBL Partybox 720 at $1,099.95 if you want a large party speaker. Buy the Sony ULT Tower 5 at $448 if you want a party speaker instead.
