GentleYAG Pro (suggested 10 sessions) Or, Cutera Excel HR - ND YAG (suggested only 6 sessions)

I am an Iranian (medium/olive skin) considering getting laser hair removal. I know ND:YAG is best n but does the machine make a difference? I received quotes from two salons and trying to decipher which one to go for? GentleYAG Pro (salon suggested I get 10 sessions) or Cutera Excel HR - ND YAG (is more expensive but the salon suggested I will only need 6 sessions)... HELP!
