As you can tell, both of the cameras posses different megapixel count and different sensor sizing. The FS42 having a tinier sensor is going to make shooting shallow DOF tougher and the Sony TX20 will offer extra detail because of its extra 6MP. Higher resolution will also let you crop shots somewhat more aggressively. The older FS42 is going to be disadvantaged with regard to sensor technology.
