Short answer: the Soundcore Motion 300. It ranks #2 of 134 medium speakers at $79.99; the Bose Soundlink Flex 2nd gen ranks #33 and costs $129, so there is not much of a tradeoff to weigh.
What the Bose Soundlink Flex 2nd gen gets right: Pretty much identical sounding to the 1st gen. Set against that: Not stereo.
On the Soundcore Motion 300 side: Pretty deep bass for the small size. Set against that: Without the above EQ or turning the top 2 treble EQ bars to max.
Buy the Bose Soundlink Flex 2nd gen if the price matters more than the ranking. Buy the Soundcore Motion 300 if the ranking matters more than the price.

Bose Soundlink Flex 2nd gen: $129.00 Amazon
Pros: Pretty much identical sounding to the 1st gen
Cons: Not stereo. Warm sounding with overly boosted bass which drowns out midrange detail. Self drains the battery about 10% a week.

Soundcore Motion 300: $79.99 Amazon
Pros: Pretty deep bass for the small size. Pocket size in a big pocket. Can be used in stereo facing you, or omnidirectional lying down. Ability to have a custom EQ for each orientation, standing, lying flat, hanging. Try the Uboom L EQs from Oluv for a more neutral sound.
Cons: Without the above EQ or turning the top 2 treble EQ bars to max, this speaker is very rolled off in the treble and will rank around #50 in the rankings. Bassup mode is worse than Signature. Not quite as detailed or neutral as higher ranked speakers. Slight bass distortion when turned up.
