Depends on how far back you want to look at. Some of their early projects 15 years back like Aman Perdana, Garden Residence and Kinrara Residence actually not bad. It started going downhill when they get too greedy during the 2012-2015 property boom by pricing high density development at future prices and of course delivering shitty products like the Icon City.

Merely commenting from price appreciation point of view, and not bad doesn't mean it is very good. I don't stay in any of the projects, so can't comment on their quality.
