Which better is better: Candela Gentle, Deka Synchro Replay, or Cynosure for laser hair removal? (Photo)

Which of those machines that use alex laser is the best ( if there is a difference) for hair removal? Candela gentle - deka synchro replay - cynosure ? I'm 20 yo male with skin color type between 3-4 (pic provided) and dark black hair. I'm planing to do candela on my face+axella ; and deka for rest of body . Is that sound as a good plan? Please inform me what is my exact skin color number and what the Recommended initial alex laser wave length + joles that I would start with . Thank you! K.
