Noida Builders: Who actually delivers on time?

Guys, I'm based in Dubai and looking to invest in Noida. Can't visit easily, so need your help! Which builder delivers projects on time, yaar? I've heard mixed reviews. Also, what about hidden charges at possession? Kisi ko experience hai? I'm worried about getting surprised later. Need a property manager also... kon sahi rahega? I need peace of mind, bhai. Any advice?
