Noida upgrade: Is location premium really worth it?

Okay I'll be honest – I'm kinda confused. Currently in a 2BHK in Sector 154. Thinking of upgrading to a 3BHK near Noida Extension. Is it worth paying the extra for better connectivity vs a bigger space further out? Has anyone seen good appreciation in K V Developers projects lately? Already have a home loan, so EMI is a big factor. Kya karoon?
