Is the 1.0 TSI Petrol Engine Worth It for My Daily Commute?

I'm considering swapping my current Seat for a newer model with the 1.0 TSI petrol engine and I'd love to hear from fellow owners about their experiences with this powerplant for daily commutes. Are the benefits of improved fuel efficiency and reduced emissions worth the added cost? Do they notice any significant differences in performance or reliability compared to other engines?
