I haven't driven the Rio yet, but if it's significantly less peppy than the un-torquey Jazz, I'd go for the Jazz.

The Jazz is more spacious and has no known major issues (ehem Gamma knocking). It's overpriced, but you might appreciate the toys it has (I don't).

If I could add another choice into the list, I'd suggest the Ford Fiesta Sport instead. Better handling than the Jazz, much cheaper, and in my opinion, looks better too.

The Rio is a good looking car with a lot of toys, but for 838k I'm expecting a 1.5/1.6L engine.

All 3 are just about as fuel efficient as each other.
