As you can tell, both of the cameras enjoy different megapixel count and different sensor sizing. The W550 with its smaller sensor will make shooting shallow DOF harder and the Sony A58 will result in more detail using its extra 6 Megapixels. Greater resolution can also make it easier to crop pics far more aggressively. The older W550 will be disadvantaged with regard to sensor technology.
