Yes Noida is the best choice. Sector 77 onwards are a good bet. Sector 32 is also witnessing good development and hence returns are expected to be high.
In Delhi NCR Noida is the best place to invest in. Noida sectors such as 77 onwards are witnessing good construction. The positive is that they are near commercial hub (Sector 18 and Sector 32) so appreciation will be good. Depending on budget you can also invest in Wave City Centre in Sector 32, Noida, where investment in commercial will be best. Appreciation in these two Noida Sectors will rise from 15,000 per sq.ft. to Rs 25,000 per sq.ft. in 2014. So you may go and check the details, see the location and then decide.
Noida and Greater Noida are still lagging behind in comparison to Gurgaon. Gurgaon has arrived as the leading residential and commercial hub. Also in terms of education Gurgaon boasts of bigger names like Sriram and Heritage, hospitals are also there with latest facilities. So I would suggest you to go with Gurgaon.
