I, am interested in purchasing MUV , options are Grande mkii Gx or Xylo E8. Which is best as per expert advice.

Xylo...

Smoother engine,
More space.

Well.. ya a good alternative to Innova but not a really upto the mark.. Same goes for MKII from TATA.

There is more difference in price of both the vehicles if your budget is poor so you will go with Grande MKII otherwise you will go with Mahindra Xylo. In both the vehicle i like xylo more space and good look... and more features....
