JBL PartyBox Stage 320 vs ION Tailgater Tough

The JBL PartyBox Stage 320 is a better speaker than the ION Tailgater Tough. It has a more balanced frequency response overall with greater extension in both the bass and treble ranges, so it's better suited for listening to a variety of music genres. The JBL also has a better soundstage with less directivity, so music sounds more consistent from various angles, and it can play audio in stereo without downmixing to mono, unlike the ION. It can get louder, too, albeit with some loss of clarity as you crank up the volume. The ION, on the other hand, is more portable, even when considering the JBL's wheels and collapsible handle.
