Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Soundcore Boom Go 3i ranks #2 of 46 small speakers at $79.99; the Soundcore Motion 300 ranks #2 of 134 medium speakers at $79.99.
What the Soundcore Boom Go 3i gets right: IP68 rated (full submersion + dustproof). The tradeoff: Sounds a bit piercing and metallic.
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 Soundcore Boom Go 3i at $79.99 if you want a small speaker. Buy the Soundcore Motion 300 at $79.99 if you want a medium speaker instead.

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.
