Short answer: the Harman Kardon Luna 2. It ranks #25 of 164 medium speakers by sound quality (rated 4.1/5) at $199.95 and is still sold new; the Tribit Stormbox Mini ranks #139 (rated 2.4/5) and is discontinued, so it is only an option used.
The Harman Kardon Luna 2 is the better-sounding pick. Articulate, spacious midrange with precise imaging and instrument separation. It has an adjustable EQ, which the Tribit Stormbox Mini lacks. Watch for: Treble can sound bright and edgy, and it loses more output off-axis than some rivals.
Why pick the Tribit Stormbox Mini: IPX7 waterproof, excellent battery life (12 hours), RGB LED lighting, app support with AAC codec, true wireless stereo (TWS) capability, USB-C charging. It supports AAC Bluetooth, which the Harman Kardon Luna 2 lacks. It keeps a wired aux input, which the Harman Kardon Luna 2 lacks. It plays in stereo from a single unit, unlike the Harman Kardon Luna 2. The tradeoff: Lacking quite a bit of bass.
Buy the Harman Kardon Luna 2. It is rated higher for sound quality; the Tribit Stormbox Mini is no longer sold new.

The Two Speakers In Full
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).
