Noida investment: Sector 164 sahi hai kya?

Guys, I'm looking to upgrade to a 3BHK near Sector 164. Wife wants a good society, safe for kids. Swaraj Homes Builders & Developer ka koi project dekh rahe the. Has anyone experienced their construction quality? Kya rent vs buy still makes sense in Noida? Also, under-construction lena sahi rahega? Mujhe advice chahiye, yaar. Kids' school admission bhi toh dekhna hai. What do you think?
