Short answer: the Minirig Mini 2. It ranks #3 of 63 small speakers by sound quality, rated 4.4/5, at $100. The Sony SRS-XB100 ranks #43, rated 2.9/5, at $63, $37 cheaper, which does not close the gap in sound quality.
The Minirig Mini 2 is the better-sounding pick. A tiny, very neutral speaker with much deeper bass than most its size, a long battery, and an optional add on subwoofer. It supports aptX Bluetooth, which the Sony SRS-XB100 lacks. It keeps a wired aux input, which the Sony SRS-XB100 lacks. It has an adjustable EQ, which the Sony SRS-XB100 lacks. The catch: Calls itself splash resistant and has no official water rating.
The Sony SRS-XB100 is the longer-running, tougher option. A pocketable waterproof speaker with a long real world battery, a clip for bags, and stereo pairing. It is rated for 16 hours of battery against 12 for the Minirig Mini 2. It is rated IP67 against Splash resistant for the Minirig Mini 2. Watch for: Not much bass.
Buy the Minirig Mini 2. It is rated higher for sound quality, and saving $37 with the Sony SRS-XB100 does not make up for the sound-quality gap.
