Short answer: the Sony ULT Field 3, if you are buying new. The Soundcore Motion 100 ranks higher than it (#45 vs #75 of 175 medium speakers, 3.7/5 vs 3.4/5) but is discontinued, so only consider it used; the Sony ULT Field 3 is still sold new at $208.
The Soundcore Motion 100 is the better-sounding, lighter choice. At 1.3 lbs (575 g) it weighs much less than the Sony ULT Field 3 at 2.6 lbs (1.2 kg). The tradeoff: Not very deep bass, slight distortion.
The Sony ULT Field 3 is the longer-running option. IP67 rated, dustproof and water resistant. It is rated for 24 hours of battery against 12 for the Soundcore Motion 100. Watch for: Sounds a bit hollow, a bit boosted in the treble.
Buy the Sony ULT Field 3 if you want one new; the Soundcore Motion 100 is discontinued, so only look for it used.

Soundcore Motion 100: $47 Discontinued eBay
Same family: the Soundcore Motion 300 (larger model, ranked higher, rated 4.5/5), the Soundcore Motion X500 (larger model, rated 4.1/5) and the Soundcore Motion X600 (larger model, rated 4.3/5). See every Soundcore Motion generation.
Pros: Use Oluv’s EQ for the flattest response. Measured bass extension of 65Hz (-10dB).
Cons: Not very deep bass, slight distortion. Real-world battery falls well short of the 12-hour claim at higher volumes (closer to 4 hours at max). Charging takes about 5 hours; no charge-out for other devices. Discontinued and no longer sold new.

Same family: the Sony ULT Field 1 (smaller model, ranked lower, rated 3.1/5), the Sony ULT Field 7 (smaller model, rated 3.2/5), the Sony ULT Tower 10 (smaller model, rated 3.9/5), the Sony ULT Field 5 (larger model, rated 3.5/5), the Sony ULT Tower 5 (larger model, rated 4.5/5), the Sony ULT Tower 7 (larger model, rated 4.7/5), the Sony ULT Tower 9 (larger model, rated 4.2/5) and the Sony ULT Tower Max (larger model, rated 4.8/5).
Pros: IP67 rated, dustproof and water resistant. 24 hour battery life. App with 10-band EQ. Party Connect with up to 100 speakers. USB-C in/out for charging your phone.
Cons: Sounds a bit hollow, a bit boosted in the treble. Custom EQ and the ULT bass-boost button can’t be used together: turning on ULT disables the EQ. Bass is very weak with ULT off. Lost to the JBL Charge 6 in a side-by-side comparison despite being the larger speaker.
