Short answer: the Bose Portable Smart Speaker, if you are buying new. The JBL Charge 4 ranks higher than it (#56 vs #68 of 150 medium speakers, 3.5/5 vs 3.4/5) but is discontinued, so only consider it used; the Bose Portable Smart Speaker is still sold new at $399.
Why pick the JBL Charge 4: Doubles as a power bank for charging phones/tablets. The catch: Not stereo.
What the Bose Portable Smart Speaker does well: Both Alexa and Google Assistant are built in, and RTINGS rates its microphones as excellent at hearing commands from far away or in a noisy room. The tradeoff: RTINGS found the out of the box tuning boomy and says it doesn’t get very loud; the app’s bass and treble sliders help, and SoundGuys recommended cutting bass by 10 to 20 steps to balance it.
Buy the Bose Portable Smart Speaker, since the JBL Charge 4 is discontinued and only worth hunting down used.
There is a real gap in water resistance: the JBL Charge 4 at IPX7 (brief submersion) against the Bose Portable Smart Speaker, which has IPX4 (splashing).

Bose Portable Smart Speaker: $399.00 Bose eBay
Pros: Both Alexa and Google Assistant are built in, and RTINGS rates its microphones as excellent at hearing commands from far away or in a noisy room. It works as a Wi-Fi speaker at home (AirPlay 2, Chromecast built-in, Spotify Connect) and as a Bluetooth speaker away from Wi-Fi, weighs about 1 kg with a carry handle, and is IPX4 splash resistant. SoundGuys measured 13 hours 6 minutes of playback at 75 dB, beating Bose’s 12 hour claim, and found the bass impressive for its size, especially near a wall or corner. Its 360 degree design spreads sound evenly around a room.
Cons: RTINGS found the out of the box tuning boomy and says it doesn’t get very loud; the app’s bass and treble sliders help, and SoundGuys recommended cutting bass by 10 to 20 steps to balance it. Pushed to full volume, Tom’s Guide heard unbalanced sound and Pocket-lint found the bass struggling and turning incoherent. RTINGS measured only about 5 hours of battery in its own test. It is mono, has no aux input (the USB-C port only charges), uses Bluetooth 4.2, and the Bose Music app supports a limited list of streaming services. IPX4 covers splashes only, not submersion or dust.
