I have done quite a bit of research in the newer part of Rawang area, and moved to Rawang from Damansara Perdana about 3 years ago, still feel excited about the developments and never regretted, my vote definitely goes to Rawang.

I would like to share my view as below:
The past, the current and the future of Rawang:In the past, there have been more developments in the southern KL, and lesser developments in northern KL, due to some infamous project that does not take off in 1990s, coupled with a stronger/closer radius contender for landed at that time such as Puchong, Subang, Damansara, Rawang has not much development in 1990s. With so many people bashing this area in the past, developers and home seeker alike avoid Rawang area for many years due to the negative perception. But perception does change, especially with empty land, afterall, lands are neutral, it is the developments in within that give people the perception making them underwater, or making them fly. Perception is changing a lot in Rawang, now more people are comparing Rawang based on rationality, and when we do that, Rawang is quite attractive, about 30 km from downtown KL, G&G homes at attractive price, and vast developments in the pipeline in the future.
In recent years, this weakness in the past, which most developers avoided northern KL area in the past has IMO, turn into a strength now when the population start looking at suburb in greater radius as the population grow rapidly and the perception of rawang change, as major developers now have larger track of undeveloped land to be acquired at cheap/reasonable price suitable for township developments and they are within 30km radium from PJ/downtown KL, now there are more than 5000 acres of lands in combine that will be developed side by side by many developers in the next few years such as Guocoland, Hongbee, Tan&Tan/IGB, Bandaraya, Gamuda, Mah Sing, Glomac, Lowyat,Country garden etc. Each of those major developers will be bringing their creativity, resources, and experience in competing for home buyer, mainly for the next generation of G&G homes.
In the near future, a lot more population who prefer landed has or will shift their preference to G&G landed residences, just like in the 1990s when people shift to highrise with security and facilities from just flat/highrise in the past without security or facilities. Due to the security condition of our country, the trend now is, landed home seeker will continue to seek their homes with security and lifestyle elements, the one that G&G homes can offer them, and Rawang with such a huge track of land, with so many developers has publicly announced that they will developed their lands into G&G homes, is catering towards that trend, many with commercials too will fits into the demands by newer landed home seekers. Greater KL population is growing rapidly, we have 6 million people in 2010, and we are expecting to have 10 million people in 2020, or about a third of the country population that will live in greater KL Alone. That also means, we will need a lot more houses for the new population, and those who prefer G&G landed, from mid range to high end will start and will continue to look for their preferred G&G homes this area, as an area with the most concentrated G&G homes in the pipeline.
IMO, we are barely stretching the surface when we look at the massive change and developments in Rawang these few years, it is just a beginning, as a lot more developers, especially those more “Premium” ones, I personally belief, are waiting for more ongoing infra and amenities to “ripe” before launching their project with more impact. This 5000+ acres will soon fill the demand gap for the next generation of G&G landed home seeker, who prefer security and lifestyle of different concepts, when more developers completed their G&G project in the next few years in Rawang, more commercial will also come online. Mont Kiara is the area with the largest number of high end condo in KL for many years, undisputable. This new Rawang area shall be the area with the largest concentration of Gated and Guarded lifestyle landed Homes by different developers, a massive G&G area unique of its own, the size and magnitude of this G&G area shall be larger than anything in combination of G&G we are seeing now, if we combine, Sierramas, Jade Hills, DPC, Setia eco Park and others successful G&G developments in greater KL together, the new 5000+acres G&G area in Rawang will be larger than all those combined together, and they will be side by side
