No, EF is for Enhanced Fujita scale and F is for Fujita scale. The new scale, implemented in 2007 is more accurate, but ratings are essentially equivalent. Most tornadoes would receive the same rating on either scale.

The strongest category of tornado is EF5 (F5 in countries that still use the original Fujita scale). However, although these tornadoes are the strongest they are not always the largest. In fact, for nine years the largest tornado on record, which hit Hallam, Nebraska on May 22, 2004 was an F4. Though weaker than an F5 this is still and extremely powerful tornado.
