Short answer: it depends whether waterproofing and stereo matter, since both are budget picks. The Onn Small Rugged Speaker is called amazing value for the money, though its bass isn’t quite as deep as the top ranked models. The Xiaomi Mi Portable Mini adds IP67 waterproofing, TWS stereo pairing, a 10-hour battery, Bluetooth 5.0, a compact 0.4 lbs (185 g) design and a bass boost equalizer, though it also has not much bass and rolled off treble.
Buy the Onn Small Rugged Speaker. It is rated higher for sound quality than the Xiaomi Mi Portable Mini and costs less, which makes it the one to get unless you need something the other one does better.
