As you can tell, each of the cameras enjoy different megapixels and different sensor sizing. The E-450 due to its smaller sensor is going to make getting shallow depth of field harder and the Olympus E-450 will show more detail having its extra 4MP. Greater resolution will help you crop photos far more aggressively. The more modern E-450 should have an advantage with regard to sensor innovation.
