I would go with SS since there is no price difference. Also, unless those cabinets are more worn than they appear from your pictures, there doesn't look like there is anything wrong with them and they're really not out of style. Maybe you can pass by the all white trend and leave them alone. I can't see your floors. If you paint the cabinets white is that going to work with the floors? No matter what you decide to do, you do need a new light fixture.
