Short answer: the Marshall Stockwell II, with the Everboom’s data still thin. The Everboom has little data so its ranking may shift, and it carries an upper bass boost with a warm, rolled-off treble and bass that does not dig deep. The Stockwell II is possibly the most natural Marshall speaker with excellent off-axis performance, though it is not stereo, is not very loud and adds a DSP reverb some may find annoying.
Buy the Marshall Stockwell II. It is rated higher for sound quality, and the $112.82 saving on the Ultimate Ears Everboom is not enough to make up the difference.
Water resistance is not close: the Ultimate Ears Everboom is rated at IP67 (brief submersion), well ahead of the Marshall Stockwell II at IPX4 (splashing).

Marshall Stockwell II: $229.99 Amazon eBay
Newer model: the Marshall Stockwell III, ranked lower, rated 3/5.
Pros: Marshall Stockwell II uses 3” woofer, 2x 2” fullrange tweeters. Its 1.4 kg, claimed 20 hours (Manufacturer specified) battery life, IPX4 protection, aux input, up to 96dB and mono playback make it a practical option for its intended room or portable use. Possibly the most natural sounding Marshall speaker, with excellent off-axis sound. Measured bass extension of 44Hz (-10dB).
Cons: Bass is limited by its 44Hz specification. There is no companion app. No EQ adjustment. Not very loud, and the added DSP reverb may annoy purists.
