These sit in different size classes, so this is not a straight ranking comparison. The Bose SoundLink Plus ranks #25 of 82 large speakers by sound quality at $269; the Harman Kardon Luna 2 ranks #23 of 144 medium speakers by sound quality at $199.95.
Different sizes. The SoundLink Plus is a large speaker at 1.5 kg with four passive radiators. The Luna 2 is a medium speaker at 735 g. Each is rated within its own class.
The Luna 2 is the more refined listen. Reviews describe an articulate, spacious midrange with precise imaging, and tight bass that stays clean at volume. Its weak points are treble that can turn bright and edgy and a claimed 12 hours of battery. It has an app EQ, and two units pair via AirTouch for true stereo.
The SoundLink Plus trades refinement for runtime and features. It plays in stereo from one unit, lasts close to 20 hours, and charges a phone over USB-C. Its bass is boosted and thuddy, and it has no EQ adjustment, so what you hear out of the box is what you get.
Both are IP67, so either survives a pool deck or a rainy campsite.
Buy the Bose SoundLink Plus at $269 for a large speaker, or the Harman Kardon Luna 2 at $199.95 for a medium speaker instead.

The Two Speakers In Full
Bose SoundLink Plus: $269.00 Amazon eBay
Pros: IP67 rated, IP67 water/dustproof. Close to 20 hour battery life. Vibrant sound with booming bass, clean mids. Bluetooth 5.4 with good range. Premium tactile grille, smooth silicone. Quality build at $269.
Cons: Boosted thuddy bass, but not as deep as the SoundLink Flex and you should probably just buy one of those instead if you want a Bose.

Harman Kardon Luna 2: $199.95 Amazon B&H Photo Video eBay
Older model: the Harman Kardon Luna (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).
