Short answer: the Harman Kardon Luna 2 if sound quality matters most, the Klipsch Groove if price matters most. The Harman Kardon Luna 2 ranks #24 of 157 medium speakers, rated 4.1/5, at $199.95. The Klipsch Groove ranks #105, rated 2.8/5, at $9, $190.95 cheaper.
The Harman Kardon Luna 2 is the better-sounding, longer-running choice. Articulate, spacious midrange with precise imaging and instrument separation. It is rated for 12 hours of battery against 8 for the Klipsch Groove. It is rated IP67 against IPX4 for the Klipsch Groove. It has an adjustable EQ, which the Klipsch Groove lacks. Watch for: Treble can sound bright and edgy, and it loses more output off-axis than some rivals.
What the Klipsch Groove does well: Pretty balanced sound in a compact, splash-resistant form factor. It supports AAC Bluetooth, which the Harman Kardon Luna 2 lacks. It keeps a wired aux input, which the Harman Kardon Luna 2 lacks. The tradeoff: Bass doesn’t go as deep as class leaders.
Buy the Harman Kardon Luna 2 when sound quality outweighs the price for you, and the Klipsch Groove when the price outweighs sound quality instead.

Harman Kardon Luna 2: $199.95 Amazon B&H Photo Video eBay
Older model: the Harman Kardon Luna (ranked lower, rated 4/5).
Pros: Articulate, spacious midrange with precise imaging and instrument separation. Tight, well-controlled bass from the 62mm x 82mm woofer and passive radiator despite the compact body, and it stays cleaner at volume than pricier rivals like the Sonos Play. IP67 rated, and two units pair via AirTouch for true stereo sound.
Cons: Treble can sound bright and edgy, and it loses more output off-axis than some rivals. Some listeners hear mid-range rattling on certain tracks, similar to sibling JBL models. 12-hour battery life trails category leaders like the JBL Charge 6, which doubles it. Single unit is not stereo (1.1 driver layout).

Pros: Pretty balanced sound in a compact, splash-resistant form factor. IPX4 water resistance and ~8 hour battery life make it durable for outdoor and poolside use. 3-inch high excursion full-range driver paired with dual side-firing passive radiators.
Cons: Not stereo. Bass doesn’t go as deep as class leaders. Distortion sets in at higher output levels. Older Bluetooth 4.0 architecture without app EQ.
