Short answer: the Marshall Middleton. It ranks #34 of 85 large speakers by sound quality, rated 4.0/5, at $199.99; the Sony SRS-XG300 ranks #60, rated 3.1/5, and costs $219, so there is not much of a tradeoff to weigh.
The case for the Marshall Middleton: Very deep bass for the size/weight. The tradeoff: 5db dip at 1.7kHz and 6.3kHz.
Why pick the Sony SRS-XG300: IP67 dust/waterproof rating. The catch: Overly expensive.
Worth knowing: the Sony SRS-XG300 has been discontinued and is hard to find new at this point.
Buy the Marshall Middleton. It is rated higher for sound quality than the Sony SRS-XG300 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

The Two Speakers In Full
Marshall Middleton: $199.99 Amazon eBay
Newer model: the Marshall Middleton II, ranked higher, rated 4.1/5.
Pros: Very deep bass for the size/weight. Measured bass extension of 39Hz (-10dB).
Cons: 5db dip at 1.7kHz and 6.3kHz. 9kHz treble peak. Not a very smooth frequency response. A lot of Marshall’s added dsp echo which cannot be turned off, very distracting and annoying. It’s like forcing you to listen to your music in an echo chamber. Bass is reasonably deep but artificial sounding and flabby, with no attack and no dynamics. Treble is rolled off.
