Confused about Noida investment—need your honest opinions!

I'm seriously thinking of buying a bigger flat in Noida. Need at least a 3BHK. Kids' school admission is my top priority, so location matters a lot. Has anyone invested in Sector 51 recently? Is it still a good time to buy, or is the market already too high? My budget is around 1.5cr. Also, Malik Infrahomes India Pvt Ltd ka track record kya hai? Under-construction lene mein darr lagta hai after hearing so many horror stories. Should I stick to ready-to-move only?
