Short answer: it depends on whether you need a battery. The Sony ULT Tower Max runs only on mains power, while the Teufel Rockster 2 has a battery rated for 15 hours. The Sony ULT Tower Max ranks higher on sound quality (#1 vs #5 of 13 large party speakers, 4.8/5 vs 4.7/5). Get the Sony ULT Tower Max if it will always be plugged in, or the Teufel Rockster 2 if you want to play away from an outlet.
The ULT Tower Max is the bigger, louder plug-in system. Nine drivers, including three 11-inch woofers, held about 110dB from 40 to 100Hz in AudioTribe’s outdoor test, and it adds a 10-band EQ, LDAC, RCA and XLR inputs and an XLR output. At 124.1 lbs (56.3 kg) with no battery, it stays near an outlet.
The Rockster 2 is the battery-powered alternative. A 15-inch woofer and horn-loaded tweeter give even, consistent sound off to the sides and project clearly over long outdoor distances, and its battery is rated for 15 hours. It has an XLR mic input, several line inputs and Party Link. Its bass drops off further at high volume.
Buy the Teufel Rockster 2 if you need to play away from an outlet. Buy the Sony ULT Tower Max if it will always be plugged in.
