Short answer: the Monster S380, though neither ranks well in its class. It ranks #137 of 175 medium speakers by sound quality, rated 2.6/5, at $49.99; the Boat Stone 352 ranks #153, rated 2.3/5, and costs $50, so there is little reason to consider the other one. Both are rated below 3.0/5 among the 175 medium speakers; for better sound, the EarFun Uboom L ranks #2 at $49.79.
The case for the Boat Stone 352: Retailer color edition of the Boat Stone 350, sharing identical 10W stereo hardware, dual passive radiators, and IPX7 casing. The catch: Midrange peaks with rolled-off treble.
The Monster S380 is the better-sounding, longer-running choice. Rated for 20 hours with IPX6 water resistance, Bluetooth 6.0, aux and microSD inputs, a speakerphone microphone, TWS stereo pairing and a carry lanyard for about $50. It is rated for 20 hours of battery against 6 for the Boat Stone 352. The catch: No measurements or substantive reviews, so its rating is estimated, and the 40 watt claim is unverified.
Buy the Monster S380. It is rated higher for sound quality than the Boat Stone 352 and costs less, so only choose the other one for a particular feature it does better.
Worth knowing: the Monster S380 has not been measured yet. Its rating is estimated from related models, with a likely range of 2.2 to 3.0, so treat this verdict as provisional.
