Short answer: the Teufel Boomster 4. It ranks #44 of 89 boombox speakers by sound quality (rated 3.4/5); the JBL Partybox On the Go ranks #59 (rated 3.0/5).
Why pick the Teufel Boomster 4: Warmer and more open than the Boomster 2021 it replaces, with nicer, less harsh highs, a wide stereo image from its three-way layout (two 20mm tweeters, two 65mm midrange drivers and a 110mm woofer with passive radiators) and good detail. Watch for: Side by side with the Boomster 2021 the sound barely changed, and it has a little less deep bass.
The case for the JBL Partybox On the Go: JBL Partybox On the Go uses 5.1” woofer + tweeters. The tradeoff: Bass is limited by its 49Hz specification.

Teufel Boomster 4: €249.99 Teufel eBay
Older models: the Teufel Boomster 2021 (ranked lower, rated 3.4/5) and the Teufel Boomster NG (2017) (ranked lower, rated 3.2/5).
Pros: Warmer and more open than the Boomster 2021 it replaces, with nicer, less harsh highs, a wide stereo image from its three-way layout (two 20mm tweeters, two 65mm midrange drivers and a 110mm woofer with passive radiators) and good detail. Its new treble control and remote let you tame the top end. DAB+ and FM radio, a claimed 23 hours of battery at medium volume, IPX5, Bluetooth 5.0 with AAC and aptX HD, multipoint, an aux input, USB-C charging and stereo pairing.
Cons: Side by side with the Boomster 2021 the sound barely changed, and it has a little less deep bass. Against the Harman Kardon Go + Play 3 it sounds sharper and thinner, with weaker bass and a less natural stereo image, and its bass drops off at full volume. At 3.75 kg it is heavy for its size, it has no power bank output, and IPX5 is a step down from the older model’s IPX7.

JBL Partybox On the Go: $300 Amazon eBay
Newer model: the JBL PartyBox On-The-Go 2 Plus, ranked higher, rated 4.4/5.
Pros: JBL Partybox On the Go uses 5.1” woofer + tweeters.

A wireless microphone is included. Measured bass extension of 49Hz (-10dB).
Cons: Bass is limited by its 49Hz specification. No EQ adjustment. Battery life is short, and its sound trails the rest of the Partybox line.
