I don't like the automatic in either the Swift or the Fiesta, but the Swift's is better.

The Swift drives and rides better than the Fiesta. It feels like a higher quality product with a better interior. Both are kind of tight on leg-room compared to the Honda Jazz, and the Swift's trunk is tiny, but both are better to drive than the Honda.

No word on the Rio yet, but I doubt it'll be as good to drive as the other two. It's bound to have a good interior and lots of space, though.
