Of the two options you have shortlisted, it's the Maruti Suzuki Fronx that we'd recommend. It's got the peppier engine, which will make a big difference on your highway journeys.
Given your limited usage in the city, an automatic isn't essential. Again, were you to opt for the automatic options, it's the Fronx's AMT that's superior to the one you get on the Tata Punch AMT.
