Short answer: both are discontinued, and they are rated the same for sound quality (#113 and #114 of 212 subwoofers). Either one is only an option used, so choose on condition and price. If you want one new, the Sonos Sub 4 replaces the Sonos Sub (Gen 3) and is rated 3.7/5 at $899.
The case for the Sonos Sub (Gen 2): A wireless subwoofer with two opposed woofers that pairs with Sonos soundbars and speakers, now discontinued and sold used. The tradeoff: No independent measurements yet, so its output can’t be compared with ranked subwoofers.
The case for the Sonos Sub (Gen 3): A wireless Sonos subwoofer with two opposed woofers and newer electronics, so it still works with current Sonos soundbars and speakers. The tradeoff: No independent measurements yet, so its output can’t be compared with ranked subwoofers.
Buy the Sonos Sub (Gen 2) or the Sonos Sub (Gen 3), whichever you find used in better condition; both are discontinued. For a new speaker, buy the Sonos Sub 4, which replaces the Sonos Sub (Gen 3).
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: Sonos Sub (Gen 2) 3.6 to 3.8; Sonos Sub (Gen 3) 3.5 to 3.9). Treat this verdict as provisional.
