Short answer: the W-King T9. It ranks #50 of 105 large speakers by sound quality (rated 3.6/5) at $111.23 and is still sold new; the Ultimate Ears Megablast ranks #87 (rated 2.8/5) and is discontinued, so it is only an option used.
The W-King T9 is the better-sounding, deeper-bass choice. 80W output power, 106dB max volume, 24-hour battery life, power bank function, Bluetooth 5.3 with 100ft range, TWS stereo pairing with wireless microphone, dual subwoofers, RGB lighting, MicroSD and AUX support, USB-C charging, karaoke capability. Its bass reaches about 47Hz before falling 10dB, against 64Hz for the Ultimate Ears Megablast. It is rated for 24 hours of battery against 16 for the Ultimate Ears Megablast. The catch: Peaks in the upper mids which makes it sound a bit harsh.
The Ultimate Ears Megablast is the lighter, tougher choice. Alexa integration (Wi-Fi + Bluetooth). At 2.4 lbs (1.1 kg) it weighs much less than the W-King T9 at 10.1 lbs (4.6 kg). It is rated IPX7, while the W-King T9 has no water resistance. The tradeoff: Bass is not very deep compared to the competition.
Buy the W-King T9. It is rated higher for sound quality, and the Ultimate Ears Megablast is discontinued, so it is only available used.
