Short answer: the JBL PartyBox On-The-Go 2 Plus. It ranks #5 of 113 boombox speakers by sound quality, rated 4.4/5, at $349.95; the Turtlebox Gen 3 ranks #105, rated 2.1/5, and costs $430, so there is little reason to consider the other one.
The JBL PartyBox On-The-Go 2 Plus is the better-sounding pick. A well balanced karaoke party speaker with clean bass, clear vocals, on-board vocal removal, an included wireless mic and a removable battery. It has an adjustable EQ, which the Turtlebox Gen 3 lacks. The catch: The bass has less kick and physical impact than the JBL Partybox Encore 2 or JBL Partybox Club 120, and the JBL Partybox Club 120 gets noticeably louder.
The Turtlebox Gen 3 is the longer-running, lighter choice. A loud, waterproof and crushproof outdoor speaker with a big battery, device charging and party mode linking. It is rated for 25 hours of battery against 15 for the JBL PartyBox On-The-Go 2 Plus. At 10 lbs (4.54 kg) it weighs noticeably less than the JBL PartyBox On-The-Go 2 Plus at 14.2 lbs (6.45 kg). It is rated IP67 against IPX4 for the JBL PartyBox On-The-Go 2 Plus. The catch: Sounds basically identical to the original and the Turtlebox Gen 2: each generation mainly added features, not sound quality.
Buy the JBL PartyBox On-The-Go 2 Plus. It is rated higher for sound quality than the Turtlebox Gen 3 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
