Short answer: the Soundboks Go for battery life, the Turtlebox Grande for a submersible shell. The Go runs a 40-hour battery at mid volume and 10 hours at full volume from a swappable 7.8Ah pack, and reaches 121dB max in Bass+ mode, though it is not as loud as the other Soundboks. The Grande counters with a 10-inch woofer, an IP67 shell and a 158Wh battery, but its claimed specs do not hold up. The Soundboks Go is discontinued; its replacement is the Soundboks Mix.

Buy the Turtlebox Grande at $730 for a boombox speaker, or the Soundboks Go at $799 for a party speaker instead.
If battery life is a priority, the Soundboks Go is rated for 40 hours versus 25 hours for the Turtlebox Grande.
Water resistance is not close: the Turtlebox Grande is rated at IP67 (brief submersion), well ahead of the Soundboks Go at no water resistance.
