Short answer: the Bose SoundLink Max for portability and features, the Teufel Rockster for maximum output. The Rockster is the loudest battery powered speaker around, with deeper bass than the Soundboks 2 or 3, but it is extremely heavy, not easy to carry, not stereo and only available in Europe. The Bose is IP67 rated and has a USB-C port that doubles as a charger, though it distorts above 80% volume.
Buy the Bose SoundLink Max for a large speaker, or the Teufel Rockster for a large party speaker instead.
If battery life is a priority, the Teufel Rockster is rated for 30 hours versus 20 hours for the Bose SoundLink Max.
If water resistance matters to you, the Bose SoundLink Max at IP67 (brief submersion) holds up far better than the Teufel Rockster at no water resistance.

Pros: IP67 rated - dustproof and waterproof to 1m. Up to 20 hour battery; real-world testing found 43+ hours. Deep, rich bass with neutral tuning, app EQ. USB-C doubles as device charger. Sturdy carry handle. The aux input has lower latency (about 33ms) than most Bluetooth connections. Measured bass extension of 48Hz (-10dB).
Cons: Big peak in the upper bass, dipped midrange and lots of peaks and dips above the midrange. Bass not as deep as a Boom 2. Gets distorted above 80%. Self drains the battery about 20% a week.
