It depends on certain factor but from my point of view:
- Elmina has higher density that combined with Saujana Utama resident, while Amverton has lesser density. I can't imagine all car going out from the same taman during peak hour. I've seen how busy it is during peak hour. It does not guarantee Amverton will have no jam, but at least the phase density is lower.
- It's Freehold so worth the money although Freehold = people can modify their house.
- If the developer's portfolio is good enough from the past project, that's great although expect some defect
- It's mostly a Malay area which is quite convenient for me as a Malay to find food, mosque, and et cetra.
- So far the land there is a Hill land so meaning lesser risk for flood to occur.
- Incoming Lotus's mall which damn convenient as I know the nearby area doesn't have such thing
- McDonalds is just really close next to main gate lol. Walking distance...
- 3 Petrol station nearby

Cons:
- The main road is small and Amverton exit is near traffic light, this will cause heavy jam, similar to Damansara Damai issue
- Mostly it is malay area, so not sure how non-malay could cater for non halal-food, pray area, pet friendliness, schools, amenities that is beneficial for non-malay
- The surrounding population there usually make some problem like rempit, crime, not-so-good attitude towards others, it's like you're staying and dealing with Selayang people     (sorry Selayang people)
- Very near to Pencawang TNB which might cause some risk or harm to our health

Since we last talked in Gamuda thread, if I still got the chance, I would go for Amverton instead of Gamuda. But if Amverton vs Elmina I think I would go for Elmina since I don't need travelling much as I am on forever Work From Anywhere mode.
