As you can tell, the 2 cameras have got different resolutions and different sensor dimensions. The Efina with its smaller sensor is going to make shooting shallower depth of field more challenging and the Pentax Efina will show more detail because of its extra 2 Megapixels. Greater resolution will let you crop images much more aggressively. The more aged Efina will be disadvantaged when it comes to sensor tech.
