Firstly the fact that your not sharing the server with anyone else makes a big difference as the resources available with that server are for your use only so you dont have the concern of another user hogging the resources.

Stability can often be an improvement experienced as well as better speeds.

Also you will often have more space and bandwidth available to you and the ability to run certain types of scripts and processes on a dedicated server that would otherwise not be allowed on other types of hosting, for example shared or VPS.

Because the server is dedicated it will handle processes much better and will be able to cope with busy and resource heavy websites.

Also if you find that you have plenty of excess storage space with your dedicated hosting plan and plenty of bandwidth then you can provide some hosting space to family or friends even and make a bit of money, helping to pay towards the cost of the dedicated hosting and getting use of the space and bandwidth available.

You can also have your own OS in place on the server and upgrade when you want to, naturally it will be beneficial to you if your able to learn how to install certain things yourself on the dedicated server.

Overall there are plenty of benefits from using dedicated hosting, although its more expensive than shared and VPS hosting you are getting much more flexibility, power and the ability to make money from offering hosting services from the server while still hosting your own websites and knowing that you are more in control of what can be used on the server.
