Eldeco Swagatam or The Studio - which is better?

I'm confused between Eldeco Swagatam and The Studio. Need a 3BHK for my kids' school. Eldeco ka on-time delivery track record kaisa hai, especially in Swagatam? My wife's priority is a safe neighbourhood. Heard kuch hidden charges bhi nikalte hain at possession. Is it true? Anyone faced issues with Eldeco's customer support after booking? Honestly not sure which project to choose. Should I be worried about possession delays?
