Short answer: the Soundcore Motion X600. It ranks #19 of 82 large speakers by sound quality, rated 4.3/5, at $150. The Doss Soundbox XL ranks #56, rated 3.1/5, at $75.99, $74.01 cheaper, not enough of a saving to outweigh the sound-quality gap.
Why pick the Soundcore Motion X600: Firmware 4.2.9 is a big improvement in sound quality over previous releases. Watch for: Stock frequency response is wavy.
The case for the Doss Soundbox XL: 32W output power, 100dB max volume, 10-hour battery life, IPX4 splashproof, MicroSD card slot, dual woofer setup with subwoofer, built-in microphone, TWS pairing support. Watch for: A little hollow sounding.
Buy the Soundcore Motion X600. It is rated higher for sound quality, and the $74.01 you would save on the Doss Soundbox XL does not close the gap.
If water resistance matters to you, the Soundcore Motion X600 at IPX7 (brief submersion) holds up far better than the Doss Soundbox XL at IPX4 (splashing).

Soundcore Motion X600: $150 Amazon B&H Photo Video eBay
Pros: Firmware 4.2.9 is a big improvement in sound quality over previous releases. Try this Oluv EQ for the best sound quality. Measured bass extension of 52Hz (-10dB).
Cons: Stock frequency response is wavy. Use spatial mode for best sound quality. Need a different EQ for each volume step. Dip in the upper bass around 120Hz. Rising frequency response, treble a little hot. Would be ranked around #20 without the Oluv EQ. Even with the Oluv EQ the bass isn’t very deep and the sound is still a little unnatural.
