Buy Altis 1.8 CVTi (Non-Grande) with closed eyes. Why? Because it is new engine and latest Toyota transmission introduced in Pakistan. The latest engines are transmission are good a both power and economy and driving pleasure.
I would suggest you to go for Grande, because you will get pedal shifters. I am watching Top Gears these days and noticed that most of the cars that they have on show for review have pedal shifters and it is fun to downshift or upshift whenever one feels the need for it and rest of the time drive it as an automatic car.
If you have budget always go for top the line variant.
