Short answer: the Bose Soundlink Revolve+ on measured sound quality, the Ultimate Ears Wonderboom 4 on price. The Bose Soundlink Revolve+ ranks #46 of 136 medium speakers at $230. The Ultimate Ears Wonderboom 4 ranks #84 at $59.99, $170.01 cheaper.
What the Bose Soundlink Revolve+ offers: True 360° sound stays consistent no matter where you stand. Built-in carry handle, useful even with wet hands; can hang from a hook via carabiner. ~12 hour battery at medium-high volume. Watch for: Overly boosted bass, warm sounding. Boosted mids. Rolled off treble.
What the Ultimate Ears Wonderboom 4 offers: Small size. Watch for: Bass isn’t as deep as the top-ranked speakers and is a little thuddy. Not much improvement over the previous Ultimate Ears Wonderboom 3 besides the USB-C charging port.
Buy the Bose Soundlink Revolve+ if sound quality is the priority over the price, or the Ultimate Ears Wonderboom 4 if the price is the priority over sound quality.
