CMV: Skyrim's One-Handed Weapons are Objectively Superior to Two-Handed Ones.

Here's why:

1) They are significantly faster, making it less likely that your opponent can dodge or block your blow after you begin your swing. You can also make more hits in the same time period, essentially cancelling out the additional damage of two-handed weapons. 

2) They are more versatile. If you wield your weapon in your right hand, for example, the left can: hold a shield (upping your armor rating, and making it easier to block blows), wield an additional one-handed weapon (increasing damage dealt), or use magic (opening up several possibilities for new skills and perks).

3) Characters, especially relatively small characters (elves, women, thin Nords in light armor), look awkward and cumbersome carrying them around on their back AND using them in battle. Sure, they look more intimidating, but there are plenty of other, easier ways, such as war paint, various types of armor, even intimidating-looking bows and one-handed weapons.

CMV! :)

Edit: To be clear, I mean that one-handed weapons are superior specifically from the point of view of the player, not NPC's.

Two-handed weapons have superior range. With proper positioning you can walk backwards and hit your opponent without taking any damage. Additionally a higher base damage means you do more damage to heavily armored opponents. It also allows you to execute them at a much higher health. The sideways power attack perk can also allow you to easily defeat massed opponents. Bashing with a two-handed weapon is also quite energy efficient and allows you to chain together a long series of attacks while you keep staggering your opponent.

The increased ability to avoid damage entirely is especially important on the highest difficulties as all enemies hit very hard even through blocks.
