Short answer: the Brane X for the higher ranking, the Minirig mk4 with subwoofer for the lower price. The Brane X ranks #4 of 75 large speakers at $500. The Minirig mk4 with subwoofer ranks #5 at $290, $210 cheaper.
What the Brane X gets right: Very deep bass, the absolute deepest from this category. The tradeoff: Boosted upper bass ~120hz, rolled off treble, so it’s missing detail up top.
On the Minirig mk4 with subwoofer side: Very balanced sound. Set against that: Not stereo, app is buggy.
Buy the Brane X if the ranking matters more than the price. Buy the Minirig mk4 with subwoofer if the price matters more than the ranking.

The Two Speakers In Full
Brane X: $500 Amazon
Pros: Very deep bass, the absolute deepest from this category. Medium bass boost is the most balanced.
Cons: Boosted upper bass ~120hz, rolled off treble, so it’s missing detail up top. Battery life isn’t great in real world use. High priced. Annoying robot voice announcements. A lot of aux input latency.

Minirig mk4 with subwoofer: $290 Minirigs
Pros: Very balanced sound. Finally USB-C charging
Cons: Not stereo, app is buggy. Wireless TWS pairing is buggy. Not easy to carry on the go, no handle and there’s 2 pieces. Calls itself splash resistant but has no official water rating. A bit expensive. Has reliability issues more often than any other speaker
