The most beaten-up topic on PakWheels - I would suggest you use the search function and read the million arguments we have had on Honda vs Toyota.
At the end its a matter of personal choice, and a person normally knows instinctively whether he's a Toyota man or a Honda man, just like Coke vs Pepsi, Dell vs HP, Ferrari vs Porsche. Learning all the pros and cons of Hondas and Toyotas will be nullified the moment you drive one and the feel of it will win you over.
