Hrm to be fair - I think one makes decision based on the market situation, and the future.

Back in March, the economy was looking gloomy indeed. LRT plans were also fishy, it would seem the federal government was all out against any non-BN state projects.
So indeed, Pai's analysis is correct during that time.

3 months later, we made some sort of a V-shaped recovery, along with all the stimulus and ever low interest rates. LRT plans suddenly goes ahead.
These were all quite unexpected, and it had nothing to do with the developer, but rather purely a change in consumer behaviour, confidence and risk taking.
This was surely bound to happen, but maybe no one expected it to be so quickly.

So, the data now is quite different compared to the past. It will also, requires change the valuation and decisions one make.

Since I have no vested interest in any of the above, thought I will just pitch in something

I think to compare SW vs Zest, both being first phases high rise condo, Puchong area with access to LRT, and relatively close proximity (except maybe SW has better access to larger roads and commercial centers) - it seems to coming down to a fight between developers - and if it's worth your money paying for that.

My opinion is, SP Setia and Zest are targeting different markets, with the former focusing not just on providing a shelther, but also lifestyle and living.
If I'm choosing for own stay, definately SW over Zest.

But for investment, since it's about profit/loss and ROI - SW's higher price makes it less attractive. Also, there're landed props within the range available in Puchong as well.
Zest is about 30% cheaper psqf basis, but you probably get what you're paying for.

So which one? Different people, different answers...
