Short answer: the W-King X10, if you are buying new. The Teufel Boomster 2021 ranks higher than it (#45 vs #77 of 89 boombox speakers, 3.4/5 vs 2.3/5) but is discontinued, so only consider it used; the W-King X10 is still sold new at $80.
Why pick the Teufel Boomster 2021: Teufel Boomster 2021 uses 1x 110mm (4.3”) woofer + 2x 65mm midrange drivers + 2x 20mm tweeters. The catch: There is no companion app.
What the W-King X10 does well: 70W RMS output with 120W peak power, exceptional 42-hour battery life, power bank function, IPX6 waterproof, 106dB max volume, EQ with indoor/outdoor modes, dual woofers with tweeters and passive radiators, Bluetooth 5.0 with 100ft range, MicroSD and USB playback, AUX input, TWS stereo pairing. Watch for: Heavily rolled off treble, less bass than the top ranked.
Buy the W-King X10, since the Teufel Boomster 2021 is discontinued and only worth hunting down used.
