Short answer: the Brane X for bass, not for polish. It has the absolute deepest bass in this category and its medium bass boost is the most balanced, but boosted upper bass around 120Hz and rolled-off treble leave it short on detail, and it adds mediocre real-world battery life, a high price, robot voice announcements and aux input latency. The DALI Katch G2 is pretty neutral but loses bass after 40% volume and is called horribly overpriced.
Buy the Brane X. 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.
There is a real battery-life gap here: the DALI Katch G2 is rated for 30 hours, the Brane X only 12 hours.
