Short answer: the Marshall Kilburn II for battery and durability. It runs a 20W Class D amp with dual 8W tweeters, claims 20+ hours with a quick-charge that gives 3 hours from 20 minutes, and its rugged leather-handled, reinforced-corner build is IPX2 rated. The DALI Katch G2 is more neutral, but it loses bass after 40% volume and is called horribly overpriced.
The Marshall Kilburn II is the better-sounding choice. A rugged 5.5 lbs (2.49 kg) stereo speaker with a 20+ hour battery, quick charging and a leather handle with reinforced corners. The tradeoff: Boosted upper bass, not very detailed, not as deep bass as competitors, upper mids peak.
Buy the Marshall Kilburn II. It is rated higher for sound quality than the DALI Katch G2 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
If battery life is a priority, the DALI Katch G2 is rated for 30 hours versus 20 hours for the Marshall Kilburn II.
Water resistance is not close: the DALI Katch G2 is rated at IPX7 (brief submersion), well ahead of the Marshall Kilburn II at IPX2 (light drips).
