It is good that you made your own decision to buy a property, after considering some plus factors vs some bad one. Actually it is your own money, hence u are entitled to a decision of your own.
Me too, I bought a property in CJ and happily moving in.
Even in the most democratic country in the world let say USA ? , I still do not like the free shooting everywhere so frequently in that country.
Can u really sleep well if such thing is happening near the place u are staying like if with ..USA scenario

but for me I can sleep peacefully in Cyberjaya.
So draw your own list of pro and con, if you prefer to stay in a very congested area/traffic, then put it as a pro , actually no right or wrong thing, remember just your own choice.

And do not be a slave to others, by allowing them to make a decision for you.
Best of luck.
Actualy my wife and i like this area very much. very peaceful, less congested. it not like the area i staying now at kl and the place i worked. Jammed everyday, polluted, very frustrated.
since this is my last property investment. so we decide to choose a place we like. Dont care about the rental or over supply issue. we decided to buy something we like.
