Short answer: the Bose S1 Pro+ for a compact, flexible system, the Turtlebox Grande for battery life. The S1 Pro+ is extremely compact and light with flexible placement, a three-channel mixer and Auto EQ, though it distorts above two thirds volume with full range music and suits voice amplification better. The Grande has a 10-inch woofer, an IP67 shell and a 158Wh battery, but its claimed 126dB does not hold up.

Buy the Turtlebox Grande at $730 for a boombox speaker, or the Bose S1 Pro+ at $699 for a battery-powered PA speaker instead.
If battery life is a priority, the Turtlebox Grande is rated for 25 hours versus 11 hours for the Bose S1 Pro+.
Water resistance is not close: the Turtlebox Grande is rated at IP67 (brief submersion), well ahead of the Bose S1 Pro+ at no water resistance.
