Short answer: the Bose Soundlink Flex. It ranks #34 of 136 medium speakers by sound quality at $89; the Bose Soundlink Revolve+ II ranks #45 and costs $269, so there is not much of a tradeoff to weigh.
What the Bose Soundlink Flex offers: IP67 rated; rugged enough to survive drops from several feet and floats. Set against that: Not stereo. Warm sounding with overly boosted bass which drowns out midrange detail.
The case for the Bose Soundlink Revolve+ II: True 360° sound stays consistent no matter where you stand around it, unlike most portable speakers. The catch: Overly boosted bass, warm sounding.
Buy the Bose Soundlink Flex. It ranks higher for sound quality than the Bose Soundlink Revolve+ II and costs less, so there is no real case for the other one.
