Short answer: a real toss-up, the Stockwell II for natural sound and the SoundLink Plus for IP67. The Stockwell II may be the most natural sounding Marshall speaker, but it is not stereo. The SoundLink Plus is IP67 rated, yet its bass is boosted and thuddy without going as deep as the SoundLink Flex, which the notes suggest buying instead.
Buy the Marshall Stockwell II. It is rated higher for sound quality, and saving $50.99 with the Bose SoundLink Plus does not make up for the sound-quality gap.
Water resistance is not close: the Bose SoundLink Plus is rated at IP67 (brief submersion), well ahead of the Marshall Stockwell II at IPX4 (splashing).

The Two Speakers In Full
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.

Bose SoundLink Plus: $179.00 Amazon eBay
Pros: IP67 rated, IP67 water/dustproof. Close to 20 hour battery life. Vibrant sound with booming bass, clean mids. Bluetooth 5.4 with good range. Premium tactile grille, smooth silicone. Quality build at $179.
Cons: Boosted thuddy bass, but not as deep as the SoundLink Flex and you should probably just buy one of those instead if you want a Bose.
