These are not really the same size class, and that is the honest framing here. The Bogasing G4 ranks #23 of 134 medium speakers at $39.59; the JBL Go 4 ranks #25 of 46 small speakers at $39.95.
What the Bogasing G4 gets right: Clear sound with punchy bass, exceptional 24-hour battery life, IPX7 waterproof, multiple sound modes for different music styles. The tradeoff: Some boosted treble that’s wavy up top.
On the JBL Go 4 side: A little more bass than the Go 3 and they fixed the strange mids peak. The tradeoff: Not much bass at all, especially with electronic/bass-heavy tracks pushed past ~50% volume.
Buy the Bogasing G4 at $39.59 if you want a medium speaker. Buy the JBL Go 4 at $39.95 if you want a small speaker instead.

Pros: A little more bass than the Go 3 and they fixed the strange mids peak.
Cons: Not much bass at all, especially with electronic/bass-heavy tracks pushed past ~50% volume. Midrange can sound grainy and treble a bit sizzly; loses clarity at higher volumes.
