I came from a Honda Fit Sport manual. Size-wise they feel very similar from the cockpit although the Fit has much more cargo hauling capabilities. Interiors are comparable as far as plastics and quality. The Fits driving position was slightly better due to the steering wheel telescoping further toward the driver. Exterior the Prius C seems to be a little better build quality as far as gaps and seals it seems absolutely perfect! The Fit was a little more fun to drive and handled slightly better, felt lighter and more tossable but was also much louder in regards to road and engine noise especially at highway speeds. It also got blown around alot more. The C feels much more planted like you are in a larger heavier car and is very quiet at speed with the exception of some wind noise. It also handles very well but doesn't quite match the Fit's steering. Loving my C and wish I could have kept both cars, the Fit for the fun aggressive driving and the C for that laid back quiet relaxed driving. I'm curious to hear others comparisons to their old cars.
