Short answer: the JBL Partybox 330 for bass and battery power. It adds an optical TV input, USB-C lossless playback, dual mic and guitar inputs, a removable battery and 280W versus the 310 and Stage 320’s 240W, though its sound is nearly identical to those two despite the bump and it is very large. The Samsung MX-ST50B sounds reasonably balanced but its bass is not as deep as a Partybox 110 and it must be plugged in to reach higher volume.
Buy the JBL Partybox 330. It is rated higher for sound quality, and the Samsung MX-ST50B is discontinued, so it is only available used.
