Short answer: the W-King H330. Both are rated 3.8/5 for sound quality (#31 and #26 of 89 boombox speakers), and the W-King H330 costs $119.99 against $349.95 for the JBL Boombox 3, with sound quality a draw, the lower price decides it.
Why pick the JBL Boombox 3: IP67 rated. The tradeoff: Dips in mid bass range which makes the bass sound undefined, bass boosted, peaky at 700Hz, not quite as good mids and treble as the Blast.
What the W-King H330 does well: In Jagist’s side by side tests it was picked over the JBL Xtreme 5, came very close to the Harman Kardon Go + Play 3 with cleaner vocals, and sounded clearer and more balanced than the Tronsmart Fiitune X30. The tradeoff: It isn’t very loud, and the W-King X20s plays louder with punchier bass.
Buy the W-King H330. Both are rated the same for sound quality, and it costs $229.96 less than the JBL Boombox 3.

W-King H330: $119.99 Amazon eBay
Pros: In Jagist’s side by side tests it was picked over the JBL Xtreme 5, came very close to the Harman Kardon Go + Play 3 with cleaner vocals, and sounded clearer and more balanced than the Tronsmart Fiitune X30. A 5.5 inch woofer, two 2.5 inch tweeters and a down firing passive radiator give it deep, full bass for its size. A 50Wh battery with 45W USB-C fast charging (about 1.8 hours), Bluetooth 5.4, stereo pairing, a bass boost button, aux, TF card and USB playback, and ambient lighting.
Cons: It isn’t very loud, and the W-King X20s plays louder with punchier bass. Below about 20% volume its DSP makes the bass cut in and out. The factory tuning is V shaped: Storytripper HD found the vocals thin and dry next to the fuller JBL Authentics 300, and the mids can sound recessed. No handle, no app, no water resistance rating, and W-King rates the battery at about 9 hours at 70% volume.
