Short answer: the JBL Partybox Encore. It ranks #6 of 73 boombox speakers by sound quality at $230; the Harman Kardon Onyx Studio 5 ranks #19 and costs $499.99, so there is not much of a tradeoff to weigh.
On the JBL Partybox Encore side: A great sounding somewhat boosted bass party speaker. 2 included wireless microphones. Watch for: Only 10 hours of battery at medium volume. Poor water rating.
What the Harman Kardon Onyx Studio 5 offers: Elegant circular design with carrying handle. Bass-heavy with balanced mids and highs. The catch: Warm sound with boosted bass. 8 hour battery at medium volume. Not at loud as others.
Buy the JBL Partybox Encore. It ranks higher for sound quality than the Harman Kardon Onyx Studio 5 and costs less, so there is no real case for the other one.
If water resistance matters to you, the Harman Kardon Onyx Studio 5 at IPX7 (brief submersion) holds up far better than the JBL Partybox Encore at IPX4 (splashing).
