Short answer: the Soundcore Boom 2. It ranks #10 of 120 large speakers by sound quality, rated 4.5/5, at $99.99; the Turtlebox Cub ranks #85, rated 3.0/5, and costs $330, so there is not much of a tradeoff to weigh.
The Boom 2 has measured strengths: bass to about 47Hz and about 105dB of output. It needs BassUp off and a community EQ from its page for its best sound. The Cub has only listening impressions so far: loud for its size, warm and bass-forward, with some bass loss at high volume.
Toughness: the Cub is IP67 and crush resistant. The Boom 2 is IPX7, waterproof but with no dust rating.
Battery: a claimed 24 hours for the Boom 2 against 14+ for the Cub. Both have a power bank and link to more speakers of their brand.
Size: 3.7 lbs (1.68 kg) for the Boom 2, 5.3 lbs (2.4 kg) for the Cub.
Buy the Soundcore Boom 2. It is rated higher for sound quality than the Turtlebox Cub and costs less, which makes it the one to get unless you need something the other one does better.
