It largely boils down to the transmission you are opting for. If you are getting a manual, the turbo petrol is a better choice. It is smooth and tractable for city use and offers good performance for the uphill sections on your trips to Himachal. The manual is also slick, with a light clutch, so it is easy to drive in the city. However, an automatic will still make life a lot easier, and if that is what you want, then the NA petrol is your only option. As such, the 1.5-litre NA has decent performance for the hills, but it won't be as effortless as the turbo petrol. The NA will, however, be a bit more efficient in the city. Both engines are reliable, and Maruti service is generally very good. Overall, if you are regularly driving in heavy traffic, the Maruti Suzuki Brezza automatic is the obvious choice. However, if you are picking the manual, you might as well get the turbo petrol unless fuel efficiency is your top priority.
