Short answer: the JBL Partybox 300 ranks #8 of 50 party speakers by sound quality at $300; the Samsung MX-ST50B ranks #24 at $300. Close enough in price that the sound-quality gap is the deciding factor.
What the JBL Partybox 300 offers: Exceptional sound quality with crisp, crystal clear highs and midranges, hard punchy bass without muddiness. Watch for: Hard to carry, too tall, drags on the ground.
On the Samsung MX-ST50B side: Sounds reasonably balanced. Set against that: Not as deep bass as the Partybox 110 or other higher ranked speakers.
Buy the JBL Partybox 300. It ranks higher for sound quality than the Samsung MX-ST50B at the same price, so there is no real case for the other one.
If water resistance matters to you, the Samsung MX-ST50B at IPX5 (water jets) holds up far better than the JBL Partybox 300 at no water resistance.

The Two Speakers In Full
JBL Partybox 300: $300 Discontinued
Pros: Exceptional sound quality with crisp, crystal clear highs and midranges, hard punchy bass without muddiness. 2x 6.5” woofers + 3x 2.25” tweeters, bass boost function, 45Hz-20kHz frequency range. 18-hour battery with 10400mAh capacity. Multiple inputs (RCA, USB, 3.5mm aux, mic, guitar). LED light modes (meter/pulse/party). True Wireless Stereo pairing up to 2 units.
Cons: Hard to carry, too tall, drags on the ground. Max spl and bass extension are only as good as the Partybox 100. No real reason to ever get one, get a Partybox 100 instead. Note, JBL daisychain is not compatible with any other non-JBL speaker and is possibly a fully digital signal. Discontinued.

Samsung MX-ST50B: $300 Amazon
Pros: Sounds reasonably balanced. A little tough to judge based on the sound samples, would be nice to have more comparisons.
Cons: Not as deep bass as the Partybox 110 or other higher ranked speakers. Needs to be plugged in to reach higher volume.
