^^ I tend to disagree.
As far as fuel economy is concerned, Nissan is better for sure. Noise and smoke depends on engine condition, a sealed engine of Nissan is definitely better than Corolla but rebuilt engines are mostly messed-up. The mechanics commonly advise to replace engine with a Kabli one instead of rebuilding and they are right because they lack the knowledge on nitty-gritties of nissan engines rebuilding.
The most important factor in our environment is resale and Nissan, though not uncommon, has been unable to compete corollas in resale inspite of better engine and mechanical technology and good body.
This is my opinion and observation.
