All in all, both of those cameras posses different megapixels and different sensor sizing. The ZS45 due to its smaller sensor is going to make achieving shallower depth of field more difficult and the Panasonic ZS45 will produce greater detail as a result of its extra 1MP. Greater resolution can also help you crop pics somewhat more aggressively. The more modern ZS45 provides an advantage when it comes to sensor innovation.
