Mont Kiara or Klang

Planning to join a real estate agency as a property negotiator, since I have lot of free time.Wish to learn more in property investment. I think to work as negotiators the best way to learn more and get used to it faster. Already went to two agency for a career talk, mont kiara or Klang, which area is better? Klang is familiar for me, and short distance for me to that office. Mont kiara, can learn a professional service, good property listing market.
