Short answer: the Minirig Mini 2, because the Sony XB23 loses its bass when pushed. The Mini 2 is very neutral, though it calls itself splash resistant with no official water rating. The XB23 is reasonably neutral too, but its bass drops off a ton at high levels, so it suits quieter listening. The Sony XB23 is discontinued; its replacement is the Sony ULT Field 1.
Buy the Minirig Mini 2 ($100) for a small speaker; the Sony XB23 ($100) suits a medium speaker instead.
Water resistance is not close: the Sony XB23 is rated at IP67 (brief submersion), well ahead of the Minirig Mini 2 at Splash resistant (splashing).
