Short answer: the Boat Stone 190, though neither ranks well in its class. It ranks #34 of 50 small speakers by sound quality, rated 2.9/5, at $9; the Xiaomi Mi Portable Mini ranks #40, rated 2.6/5, and costs $21.99, so there is little reason to consider the other one. Both are rated below 3.0/5 among the 50 small speakers, and the Tozo PE1, ranked #20 at $22.99, is a better place to start if sound quality matters.
Buy the Boat Stone 190. It is rated higher for sound quality than the Xiaomi Mi Portable Mini and costs less, so only choose the other one for a particular feature it does better.
