Grand Wellington better ROI than Marvella, fight me.

I'm upgrading from my current 2BHK. Maxblis Grand Wellington ka carpet area seems better than JMD Marvella Homes. Ready to move bhi hai. Is the higher price justified, considering the potential rental income? Marvella Homes is cheaper, but will it appreciate as much? Already have a home loan, so EMI matters. Thoughts?
