Short answer: the Harman Kardon Luna. It ranks #22 of 137 medium speakers by sound quality at $290.99; the Sonos Play ranks #48 and costs $299, which makes this an easy call rather than a real tradeoff.
On the Sonos Play side: Genuinely wide, clean stereo dispersion off-axis thanks to the two angled tweeters, holding up from the side far better than most portables. Loudness processing keeps it sounding full-bodied at low volume. Set against that: Bass distorts noticeably on bass-heavy tracks at default settings, and the distortion persists even after enabling Trueplay tuning and manually pulling bass back in the app. Sounds boxy and short on clarity next to cheaper competitors.
What the Harman Kardon Luna gets right: Pretty balanced sound besides the boosted bass. The tradeoff: Not stereo. Boosted bass, not as detailed as higher ranked speakers
Buy the Harman Kardon Luna. It ranks higher for sound quality than the Sonos Play and costs less, so there is no real case for the other one.
If battery life is a priority, the Sonos Play is rated for 24 hours versus 12 hours for the Harman Kardon Luna.

Cons: Bass distorts noticeably on bass-heavy tracks at default settings, and the distortion persists even after enabling Trueplay tuning and manually pulling bass back in the app. Sounds boxy and short on clarity next to cheaper competitors.
