Short answer: the Soundcore Select 4 Go. It ranks #25 of 62 small speakers by sound quality, rated 3.3/5, at $22.99. The Onn Small Rugged Speaker ranks #35, rated 3.1/5, at $14.88, $8.11 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Soundcore Select 4 Go is the longer-running choice. A very inexpensive waterproof mini speaker with a strap, a long battery, app EQ, and stereo pairing. It is rated for 20 hours of battery against 10 for the Onn Small Rugged Speaker. It has an adjustable EQ, which the Onn Small Rugged Speaker lacks. Watch for: Not as deep of bass as higher ranked speakers.
Why pick the Onn Small Rugged Speaker: A very cheap, tough waterproof mini speaker with USB-C charging, an aux input, and a speakerphone mic. It keeps a wired aux input, which the Soundcore Select 4 Go lacks. It links with other speakers (Party Sync Mode), which the Soundcore Select 4 Go cannot. The catch: Its 1.5-inch driver cannot create meaningful deep bass (about 66Hz at -10dB) or the clarity and scale of better small speakers.
Buy the Soundcore Select 4 Go. It is rated higher for sound quality, and the $8.11 you would save on the Onn Small Rugged Speaker does not close the gap.
