First property jitters - Noida investment advice needed!

Since January I've been looking at 2BHKs in Noida. My budget is around 80-90L. Honestly, I'm torn between under-construction and ready-to-move. Has anyone had good experiences with Arihant Group? I'm also considering Garhi Chaukhandi, but not sure about the future ROI. Rent vs buy math isn't adding up. Should I just keep renting? My parents keep saying property is always good, ab samajh nahi aa raha.
