Short answer: the Bogasing M5. It ranks #55 of 142 medium speakers by sound quality at $45.59; the Sonos Roam ranks #75 and costs $179.99, so there is little reason to consider the other one.
What the Bogasing M5 offers: Compact enough for a backpack side pocket at under 1.7 lb. Up to 30 hours of battery life. USB-C charging - no proprietary cable to lose. Watch for: Front/rear driver configuration. Use bass mode for the flattest response. Sounds thin in the midrange. Hot treble and rolled off bass in default mode. Treble a bit rolled off in bass mode.
What the Sonos Roam offers: Very neutral. IP67 rated at ~1 lb. Wireless (Qi) charging - rare for a portable speaker. Works with Alexa/Sonos Voice Control and the wider Sonos ecosystem over Wi-Fi. Watch for: Bass extension isn’t very good. Not stereo. Gets distorted if you turn up the bass.
Buy the Bogasing M5. It ranks higher for sound quality than the Sonos Roam and costs less, so there is no real case for the other one.
If battery life is a priority, the Bogasing M5 is rated for 30 hours versus 10 hours for the Sonos Roam.
