Short answer: the Soundcore Select Pro on price, the Marshall Middleton II for bass depth. The Middleton II at $330 goes very deep for its size and weight, but its boosted bass drowns out the midrange, with a dip around 200Hz, a peak at 1kHz and a dip at 1.6kHz. The Select Pro at $80 sounds almost exactly like the Motion Boom, with boosted bass and rolled-off treble.
Buy the Marshall Middleton II if you want one new; the Soundcore Select Pro is discontinued, so only look for it used.

The Two Speakers In Full
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.

Pros: Very deep bass for the size/weight. Measured bass extension of 38Hz (-10dB).
