Better area for construction of house in 2017

I want to buy a plot to construct house purely for residential purpose. My budget for plot is 45lac.

My preference is being in a ~15km radius to faizabad. And close to schools. After some research i have come up with two options.

1- bahria enclave sector n
2 - jinnah gardens

Bahria enclave offers 5 marla plots in that range. Whereas jinnah garden offers 7 marla plots in that range.

I want the construction to complete in 2017.

So given these circumstances, what would the experts suggest ?
