Short answer: the Bose Soundlink Revolve+ II, if you are buying new. The Bose Soundlink Revolve+ ranks higher than the Ultimate Ears Boom 4 (#53 vs #113 of 175 medium speakers) but is discontinued; its replacement, the Bose Soundlink Revolve+ II, is rated 3.6/5 at $299 and is still sold new.
The Bose Soundlink Revolve+ is the better-sounding option. True 360° sound stays consistent no matter where you stand. It keeps a wired aux input, which the Ultimate Ears Boom 4 lacks. The tradeoff: Overly boosted bass, warm sounding.
The Ultimate Ears Boom 4 is the lighter, tougher choice. IP67 rated, floats, and finally charges via USB-C instead of the older Booms’ Micro-USB. At 1.4 lbs (620 g) it weighs noticeably less than the Bose Soundlink Revolve+ at 2 lbs (910 g). It is rated IP67 against IP55 for the Bose Soundlink Revolve+. It has an adjustable EQ, which the Bose Soundlink Revolve+ lacks. The tradeoff: Not much improvement over the old ones.
Buy the Bose Soundlink Revolve+ II, the replacement for the discontinued Bose Soundlink Revolve+; it is rated higher for sound quality than the Ultimate Ears Boom 4.
