If you want the thrill of a typical road bike, but with the added assistance of a motor to make hills easier (or simply to help get you home!), then an electric road bike is well worth considering. Commuters can also consider them too, especially if they come with the flexibility of adding pannier racks and mudguards.
The best electric road bike is one that is ideally suited to your needs. Think about weight if you are using it primarily for commuting or consider range if you are hoping to cover lots of distance.
