Short answer: the Brane X if sound quality matters most, the Teufel Rockster Cross if price matters most. The Brane X ranks #4 of 115 large speakers, rated 4.6/5, at $549. The Teufel Rockster Cross ranks #23, rated 4.2/5, at $199.99, $349.01 cheaper.
The Teufel Rockster Cross is the longer-running, lighter option. A splash resistant speaker with fairly neutral, vocal focused sound and punchy, controlled bass that suits rock and jazz. It is rated for 16 hours of battery against 12 for the Brane X. At 5.3 lbs (2.4 kg) it weighs noticeably less than the Brane X at 7.7 lbs (3.5 kg). Watch for: Outdoor mode can sound somewhat harsh due to the 4kHz peak.
The Brane X is the better-sounding, deeper-bass pick. A portable speaker with extraordinarily deep bass for its size, plus Wi-Fi, AirPlay, Alexa and a low latency aux input. Its bass reaches about 31Hz before falling 10dB, against 51Hz for the Teufel Rockster Cross. It is rated IP57 against IPX5 for the Teufel Rockster Cross. It supports aptX HD Bluetooth, which the Teufel Rockster Cross lacks. The tradeoff: The front-facing design has only moderate dispersion, so sound changes noticeably off to the sides or behind it.
Buy the Teufel Rockster Cross when the price outweighs sound quality for you, and the Brane X when sound quality outweighs the price instead.
