Rouge Pro G4 vs Bon Charge Max
The Max is the cheaper of the two at $999, so it wins on value if the specs are close enough for your use. The Pro G4 covers more wavelengths, though the extra bands have thinner research behind them than 660nm and 850nm.

Pro G4
Rouge discloses more honestly than almost anyone, publishing both measurement methods with distances. Even so, an independent tester came in a third below their own spectrometer number.
Max
A recognised wellness brand with the vaguest irradiance disclosure in our data. Two wavelengths, no measurement distance, and the shortest warranty here.
