Short answer: both are discontinued, so this only matters if you are buying used. Used, the Sony XB33 is the better pick: it ranks #77 of 175 medium speakers by sound quality (rated 3.4/5), against #118 (rated 2.8/5) for the Sony SRS-XE300. If you want one new, the Sony ULT Field 3 replaces the Sony XB33 and is rated 3.4/5 at $208.
The Sony XB33 is the better-sounding pick. IP67 rated and lightweight (2.4 lb). The tradeoff: Not very loud.
The case for the Sony SRS-XE300: IP67 rated. The tradeoff: Muffled sounding, not very deep bass.
Buy the Sony XB33 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the Sony ULT Field 3, which replaces the Sony XB33.
