Short answer: the JBL Xtreme 4 is the more capable rugged outdoor speaker, while the Bose SoundLink Plus is a smaller premium portable with a warm, bass-heavy character. Bose ranks #25 of 97; JBL ranks #43 of 97.
SoundLink Plus has IP67 protection, a claimed 20-hour battery, USB-C power-bank output, and a quality compact build. Its bass is thuddy and not especially deep, so it is not the obvious choice for listeners seeking a balanced Bose sound.
Xtreme 4 has a replaceable battery, 24-hour claimed runtime, 100W output, 106dB maximum level, a 5-band EQ, Auracast, and stereo pairing. It benefits from EQ and has only modest off-axis consistency, but it is better prepared for loud outdoor playback.
Buy the Bose SoundLink Plus at $179 if you want the smaller premium speaker and enjoy a bass-forward presentation.
Buy the JBL Xtreme 4 at $309.95 if replaceable battery, higher output, and outdoor features are worth the larger size.

The Two Speakers In Full
Bose SoundLink Plus: $179.00 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 $179.
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.

JBL Xtreme 4: $309.95 Amazon B&H Photo Video eBay
Newer model: the JBL Xtreme 5, ranked higher, rated 4.6/5.
Pros: A rugged 2.1kg portable with IP67 protection, a replaceable battery, USB-C power-bank output, Auracast, stereo pairing and a useful 5-band app EQ. Independent reviews find the midrange detailed and the sound clear, punchy and refined for outdoor use; it also reaches a strong 106dB maximum level and has excellent real-world battery life.
Cons: It cannot produce the deep rumble of a larger speaker, and bass compression increases near maximum volume. The front-facing layout has only modest off-axis consistency, Bluetooth latency is high for video, and the default balance benefits from EQ adjustment. There is no aux input, so wired sources are not supported. Out of the box it leans bass-boosted, with a dip between the upper bass and midrange that EQ cannot fix, and it pushes the upper mids and treble at high volume. It is also expensive.
