Short answer: the JBL Partybox Encore for karaoke and party sound, the Onyx Studio 7 for a warmer tone. The Encore is a great sounding speaker with somewhat boosted bass and two included wireless microphones, but only 10 hours of battery at medium volume. The Onyx Studio 7 is warm with boosted bass, though it sounds a little sterile.
Buy the Harman Kardon Onyx Studio 7 new; the JBL Partybox Encore is no longer sold new, so it only makes sense as a used find.
Water resistance is not close: the JBL Partybox Encore is rated at IPX4 (splashing), well ahead of the Harman Kardon Onyx Studio 7 at no water resistance.

Harman Kardon Onyx Studio 7: $248.90 Amazon eBay
Newer model: the Harman Kardon Onyx Studio 9, ranked lower, rated 4.1/5.
Pros: The addition of dual tweeters gives the Studio 7 a wider, more spacious presentation than older Onyx models. It delivers strong, deep bass, useful large-room volume and can pair with a second Studio 7 for stereo. Measured bass extension of 37Hz (-10dB).
Cons: Consumer Reports finds the bass prominent and boomy, mids hazy, treble slightly smeared and the soundstage congested. Battery life remains only about eight hours, it has no water rating or advanced codecs, and it is not an especially loud outdoor speaker.
