Short answer: hard to split, so decide on bass depth and stereo. The Miatone Boompro is exactly the same as the Wisetiger P3, with slightly less bass extension than higher ranked speakers. The Bose Soundlink Flex 2nd gen sounds pretty much identical to the 1st gen but is not stereo.
Buy the Miatone Boompro. It is rated higher for sound quality than the Bose Soundlink Flex 2nd gen and costs less, so only choose the other one for a particular feature it does better.
Still deciding? The full Portable Bluetooth rankings cover every ranked option.
