Short answer: the Sony ULT Field 5. It ranks #41 of 77 large speakers by sound quality at $198; the Soundcore Trance/Rave Mega ranks #73 and costs $249, so there is little reason to consider the other one.
What the Sony ULT Field 5 offers: IP67 rated, dustproof and water resistant. 25 hour battery life. App with 10-band EQ. Party Connect with up to 100 speakers. USB-C in/out for charging your phone. Watch for: Bass not as deep as others in the category, and sound quality overall is just okay. ULT button makes a really loud tone when pressed. Just an okay speaker.
What the Soundcore Trance/Rave Mega offers: 80W power with 105dB output, BassUp technology for body-shaking bass. 20,000mAh battery for 24 hours claimed (18 hours for Trance variant). IPX7 waterproof with LED light show. USB port charges devices. Soundcore app with EQ customization, multipoint pairing, can link speakers for Party Mode. Watch for: Hugely recessed mids and treble
Buy the Sony ULT Field 5. It ranks higher for sound quality than the Soundcore Trance/Rave Mega and costs less, so the other one has nothing left to offer.
If sound quality matters at all to you, skip the Soundcore Trance/Rave Mega. It ranks near the bottom of the 77 large speakers, so look higher up the list instead.
