Short answer: the Onn Large Party gen 2 on price, the EarFun Uboom X on tuning. The Onn is an insane value at $129 versus $159.99, though it is not quite as loud as the old one. The Oluv-tuned Uboom X is the more polished pick, with the horrible out-of-the-box 0.33 firmware and EQ as its one glaring weakness.
One note: the EarFun Uboom X is discontinued, but it still ranks #1 of 113 boombox speakers by sound quality, ahead of most of what is still sold new, so it is worth considering used.
Buy the EarFun Uboom X at $159.99 for a boombox speaker, or the Onn Large Party gen 2 at $129 for a party speaker instead.
Battery life favors the EarFun Uboom X: rated for 30 hours against 12 hours for the Onn Large Party gen 2.
Water resistance is not close: the EarFun Uboom X is rated at IP67 (brief submersion), well ahead of the Onn Large Party gen 2 at IPX4 (splashing).
