BestQool Pro300 vs Rouge Pro G4
The Pro300 is the cheaper of the two at $899, 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.

Pro300
Good value for full-body coverage, but read the regulatory line carefully: 510(k) exempt is not the same as FDA cleared, and the irradiance is measured at a flattering distance.
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.
