As you have seen, both of these cameras provide different resolutions and different sensor measurements. The SX400 IS due to its tinier sensor will make shooting shallower depth of field more challenging and the Canon SX400 IS will offer more detail having its extra 1 Megapixels. Higher resolution will make it easier to crop pictures more aggressively. The fresher SX400 IS will have a benefit with regard to sensor tech.
