As you can tell, each of these cameras enjoy different megapixel count and different sensor dimensions. The E-300 with its smaller sensor is going to make achieving shallow DOF more difficult and the Sony A330 will provide extra detail using its extra 2MP. Greater resolution can also make it easier to crop photos far more aggressively. The more aged E-300 will be behind when it comes to sensor innovation.
