^^ Agreed. I would say, go with Polo TDI in case if you don't mind backseat space and want good ride quality. Service is kinda hit and miss. Micra XL would be next choice. Power is good enough and not sluggish like Grand i10 but still, backseat comfort is just OK.
Among the 2 you mentioned, Grand i10 is way to go.
