Short answer: the Soundcore Boom 3i. It ranks #31 of 166 medium speakers by sound quality, rated 4.0/5, at $118.99; the Turtlebox Ranger ranks #65, rated 3.5/5, and costs $250, so there is little reason to consider the other one.
The Boom 3i is the fuller, better-value speaker. A 94mm woofer and tweeter on 50W give warm, bass-boosted sound close to a JBL Charge 5, reaching 56Hz before falling 10dB. It is rated IP68, claims 16 hours of battery, and adds an app EQ, lights and AAC.
The Turtlebox Ranger is built to take abuse. It has the smoothest response of any Turtlebox, is IP67, and its magnets stick it to metal surfaces, with Party Mode linking to other Turtleboxes. Its bass is thuddy and not very deep, and at 2.4 lbs (1.09 kg) it is heavy for its size.
Buy the Soundcore Boom 3i. It is rated higher for sound quality than the Turtlebox Ranger and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

The Two Speakers In Full
Turtlebox Ranger: $250.00 Amazon eBay
Same family: the Turtlebox Cub (smaller model, rated 3/5), the Turtlebox Gen 3 (larger model, rated 2.1/5) and the Turtlebox Grande (larger model, rated 2.6/5). See every Turtlebox generation.
Pros: Smoother frequency response than the other Turtlebox speakers. Has magnets for attaching it to things. Appears to be quite tough
Cons: Bass sounds kind of thuddy and isn’t as deep as higher ranked speakers. Overpriced. Heavy for the size, likely due to the toughness

Soundcore Boom 3i: $118.99 Amazon B&H Photo Video eBay
Pros: Looks to be designed as a direct competitor to the JBL Charge 5 with a very similar sound profile, warm tuned with boosted bass. Better value for the money than the JBL Charge 5. Measured bass extension of 56Hz (-10dB).
Cons: Not quite as good as a JBL Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close. An earlier firmware version had some bass distortion, update your firmware in the Soundcore App
