This depends on your particular needs, as both have their advantages and disadvantages. Fan heaters are better at quickly circulating hot air, but they are less energy efficient in general since some of the electricity has to go toward running the fan rather than generating heat. Ceramic heaters also have the advantage of being quieter than fan heaters, making them great for office and studio spaces. Plus, ceramic heaters offer the added bonus of being safer than most other heaters because even though they heat up quickly, their plastic outer casing remains cool. Oil filled heaters are also safer than electric fan heaters because their effectiveness and safety doesn't depend on adequate airflow.
