If buying for a year or two, go for 1.3 Auto. In city drive 1.3 is more than enough. power difference in 1.3 and 1.6 is marginal. If want to enjoy some ride than switch to 1.8 version.
As per my experience, specially on long routes and for two way road, where you require sudden surge of power to overtake, both engines 1.3 and 1.6 with auto trans. are dull. 1.8 engine suites such situation well.
For rest of the scenarios including city and one way highway and motorway drive 1.3 is approx. equal to 1.6.
