if you want piece of mind while driving go for prosmatic.
if you want to drive fast and all that go for manual.
I have vti prosmatic for around 2 and half year and it is just an amazing ride to have. Be it long drive of 8 hours or short trip of bumper to bumper traffic, it is best aid the driver can get from its vehicle, no tension to switch between gears.
i do not know the Gass quality there in KHI but here in RWP/ISB i get as low as 3.25 rupees per kilometer while driving back and forth between the twin cities.
