Depends on what you are trying to achieve. I stuck with 19" myself and dropped the car on coilovers. The only reason I kept to the stock wheel size is because the smaller diameter tires can increase acceleration by reducing the drivetrain's effective gear ratio, which allows your engine to exert more torque per revolution, yeah I am all about speed
If it looks you want then go with the larger size wheel.
