These sit in different size classes, so this is not a straight ranking comparison. The Soundcore Boom 2 ranks #10 of 120 large speakers by sound quality at $99.99; the Soundcore Boom 3i ranks #31 of 179 medium speakers by sound quality at $118.99.
These are different sizes, not rivals. The Boom 2 is a large speaker at 3.7 lbs (1.68 kg) with a 120mm x 90mm woofer, two tweeters and 80W. The Boom 3i is a medium speaker at 1.7 lbs (783 g) with a single woofer and tweeter and 50W. Each is rated against its own size class, so the question is whether you want to carry the bigger one.
What the Boom 2 gets you: much deeper bass, reaching down to about 47Hz against the Boom 3i’s 56Hz, and around 105dB of measured output. It also has partial stereo through its two tweeters, a claimed 24 hours of battery, a USB-A power bank output and PartyCast linking. It is at its best with BassUp off and one of the community EQs linked on its page, since the stock tuning is bass heavy and a little bright.
What the Boom 3i gets you: IP68 protection against the Boom 2’s IPX7, a design that floats, a built-in microphone for calls and AAC for iPhone users. It is tuned warm like a JBL Charge 5 and sounds very close to one. The trade is less volume, less bass depth and 16 hours of claimed battery instead of 24.
Know this about the Boom 2: its processing makes some bass notes drop out at low volume, so it is not the pick for quiet background listening.
Buy the Soundcore Boom 2 at $99.99 for a large speaker, or the Soundcore Boom 3i at $118.99 for a medium speaker instead.
