Since you have already shortlisted some cars, so I will not confuse with other options.
i20 and Polo both are great cars and they have their own characteristics.
My vote if for Polo, if you love driving. Polo's FE is also decent and build quality is top class. I heard that Polo petrol engine is much better than i20. This you can confirm after test drives.
Interiors are similar in i20 and Polo, but Fabia tops in Interiors.
Feature wise, i20 is clear winner.
