Short answer: the Brane X for bass quality, the W-King T9 for features and volume. The Brane X has the absolute deepest bass in this category, but boosted upper bass around 120Hz and rolled-off treble cost it top-end detail. The T9 packs 80W output, 106dB max volume, a 24-hour battery and a power bank function, at the cost of upper-mid peaks that make it sound a bit harsh.
Buy the Brane X if sound quality matters more than the price. Buy the W-King T9 if the price matters more than sound quality.
If water resistance matters to you, the Brane X at IP57 (brief submersion) holds up far better than the W-King T9 at no water resistance.
