Short answer: the JBL Xtreme 5 for features, the Marshall Stockwell II for the most natural Marshall tuning. The Xtreme 5’s main edge is a removable battery, though it is high priced. The Stockwell II may be the most natural sounding Marshall speaker, but it is not stereo.
Buy the JBL Xtreme 5 when sound quality outweighs the price for you, and the Marshall Stockwell II when the price outweighs sound quality instead.
Water resistance is not close: the JBL Xtreme 5 is rated at IP68 (extended submersion), well ahead of the Marshall Stockwell II at IPX4 (splashing).
