The Curve and Tropicana Gardens seems much better than Atria and 3 Damansara.
In terms of Damansara Area,
One U> Paradigm> Tropicana Gardens > Pavi Damansara> Starling> Ikea> Curve> Megahrise> Atria > Citta Mall> 3 Damansara > Jaya Shopping Center> Evolve> Glo.
You need to find a niche to survive in the current market.
Atria has quite a big event space for expos and apple sales.
Starling are doing what the original Tropicana City Mall and the old Atria did, a smaller scale shopping center for those that don't want to go to big malls like One U, MV and Paradigm nearby.
3 Damansara are opening a large rock climbing space.
Glo got Worq and MRT but that's not helping much.
Tropicana gardens cannot be so top. The whole place still very empty.
You missed out The strand mall, Giza mall and Nexis mall. Not to mentioned Lotus Damansara, NSK KD and Giant KD. Further down got Emporis also. Bandar Utama got Centerpoint too.
