In terms of looks - Swift wins hands down. Liva is a simple design does not inspire any awesomeness
In terms of interiors - Swift wins it again. Although coming from a brand known of quality, Liva is full of cheap material and feels flimsy
In terms of engine - Swift wins this one too. It is more planted, driveable, peppier, gives better FE, and has better gearbox and braking.
