Short answer: the Soundcore Select Pro for value, the Middleton for deeper bass. The Select Pro sounds almost exactly like the Motion Boom, but it has boosted bass and rolled off treble. The Middleton reaches very deep bass for its size and weight, with a 5db dip at 1.7kHz and 6.3kHz as the caveat.
Buy the Marshall Middleton new; the Soundcore Select Pro is no longer sold new, so it only makes sense as a used find.

The Two Speakers In Full
Marshall Middleton: $149.99 Amazon eBay
Newer model: the Marshall Middleton II, ranked higher, rated 4.1/5.
Smaller models: the Marshall Emberton III (rated 2.7/5) and the Marshall Willen II (rated 4/5).
Pros: Very deep bass for the size/weight. Measured bass extension of 39Hz (-10dB).
Cons: 5db dip at 1.7kHz and 6.3kHz. 9kHz treble peak. Not a very smooth frequency response. A lot of Marshall’s added dsp echo which cannot be turned off, very distracting and annoying. It’s like forcing you to listen to your music in an echo chamber. Bass is reasonably deep but artificial sounding and flabby, with no attack and no dynamics. Treble is rolled off.

Soundcore Select Pro: $80 Discontinued eBay
Pros: A tough 1.5kg speaker with IPX7 protection, app EQ, a claimed 16-hour battery life, USB-C charging, power-bank output and PartyCast for linking up to 100 compatible speakers. It reaches a useful 106dB maximum level and offers a lively, bass-forward sound for casual outdoor use.
Cons: Independent lab listening finds only fair music fidelity: bass is somewhat boomy and lacks deep extension, mids can sound nasal and congested, and treble becomes smeared or sizzly. It strains at high volume, lacks an aux input and is discontinued, so it is best chosen for features and durability rather than detail or neutral sound.
