Joovv Solo 3.0 vs Rouge Pro G4
The Pro G4 is the cheaper of the two at $1,121, 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.

Joovv Solo 3.0
The category default and the one most people have heard of. Competing panels deliver similar measured output for several hundred dollars less.
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.
