By a big margin corolla. I have kept city for a quite a bit and i own a corolla atm. I am a fan of city but the suspension isnt good at all. The hard suspension does offer the advantage of slightly better handling but still i would prefer comfort over handling in a small family sedan. The few advantages of city i have found over corolla are; better handling, decent pick, better fuel economy. In other aspects Corolla is better. It is a much more comfortable car.
P.S There are may threads and posts already on this topic so do look into them for more information regarding the matter.
