As for which one is better 1.9 or 2.0 I couldn't really tell you that as its my first VW diesel. You will read many reports on here about TDI problems but they appear to be the older PD's. Only time will tell how the CR fares.
Obviously you are going to pay more for the newer CR Golfs so its a matter of shopping around and looking at the specs and what additional options they've had fitted.
