Short answer: the Miatone Boompro. It ranks #16 of 179 medium speakers by sound quality, rated 4.2/5, at $35.99; the Soundcore Boom 3i ranks #31, rated 4.0/5, and costs $118.99, so there is not much of a tradeoff to weigh.
The Miatone Boompro is the lighter option. A cheap waterproof speaker with very well balanced sound, even at full volume, and a 16 hour battery. At 1.1 lbs (500 g) it weighs noticeably less than the Soundcore Boom 3i at 1.7 lbs (783 g). The tradeoff: Slightly less bass extension than higher ranked speakers.
The case for the Soundcore Boom 3i: A warm, punchy waterproof speaker that sounds great and is a strong value. It has an adjustable EQ, which the Miatone Boompro lacks. Watch for: Not quite as good as a JBL Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close.
Buy the Miatone Boompro. It is rated higher for sound quality than the Soundcore Boom 3i and costs less, which makes it the one to get unless you need something the other one does better.
