Short answer: the Bose Soundlink Flex. It ranks #38 of 175 medium speakers by sound quality (rated 3.8/5) at $159 and is still sold new; the Soundcore Flare 2 ranks #134 (rated 2.6/5) and is discontinued, so it is only an option used.
The Bose Soundlink Flex is the better-sounding option. IP67 rated; rugged enough to survive drops from several feet and floats. The tradeoff: Warm sounding with overly boosted bass which drowns out midrange detail.
The Soundcore Flare 2 is the louder option. Try Alan Ross’s EQ for it. Alan Ross Reviews measured it at 99dB at full volume, against 96dB for the Bose Soundlink Flex. It has an adjustable EQ, which the Bose Soundlink Flex lacks. It plays in stereo from a single unit, unlike the Bose Soundlink Flex. Watch for: Rolled off treble.
Buy the Bose Soundlink Flex. It is rated higher for sound quality, and the Soundcore Flare 2 is discontinued, so it is only available used.
