Short answer: the Soundcore Boom 2 Plus, if you are buying new. The Aiwa Exos-9 ranks higher than it (#9 vs #36 of 91 boombox speakers, 4.2/5 vs 3.6/5) but is discontinued, so only consider it used; the Soundcore Boom 2 Plus is still sold new at $179.99.
The Aiwa Exos-9 is the better-sounding option. It still sounds great against current models.
The Soundcore Boom 2 Plus is the deeper-bass, longer-running pick. Quite a bit lighter than most of the other boombox size speakers. Its bass reaches about 39Hz before falling 10dB, against 44Hz for the Aiwa Exos-9. It is rated for 20 hours of battery against 10 for the Aiwa Exos-9. At 8.4 lbs (3.8 kg) it weighs much less than the Aiwa Exos-9 at 15.2 lbs (6.9 kg). The tradeoff: Warm tuning meaning a rolled off treble and some upper bass boost.
Buy the Soundcore Boom 2 Plus, since the Aiwa Exos-9 is discontinued and only worth hunting down used.
There is a real gap in water resistance: the Soundcore Boom 2 Plus at IPX7 (brief submersion) against the Aiwa Exos-9, which has no water resistance.

Soundcore Boom 2 Plus: $179.99 Amazon B&H Photo Video eBay
Older model: the Soundcore Motion Boom+ (ranked lower, rated 2.9/5).
Smaller model: the Soundcore Boom 2 (rated 4.5/5).
Pros: Quite a bit lighter than most of the other boombox size speakers. This speaker will likely move up as we get a good EQ tune that makes it a lot more neutral. Measured bass extension of 39Hz (-10dB).
Cons: Warm tuning meaning a rolled off treble and some upper bass boost. Reasonably deep bass, but not as good as the top ranked.
