Hello,

It would be best to choose the Dedicated server carefully because you will pay higher prices than other hosting service plans. However, you can consider some specific points while going for the dedicated server. Such as,

- Performance Requirements
- Potential Downtime
- Technology Advancements
- Security Features
- Technical support
-Pricing
- Back-up services
- Network Strenght

If the above points are fulfilled, you can consider that. Moreover, you can also check for the reviews of the service provider and compare them with others. Unfortunately, I don't know much about the providers you plan to consider. So I can't say anything about them. But If you ask me, I can suggest Godaddy, AccuWeb Hosting, and Hostgator. Some of them offer very advanced and good features at a reasonable price. So,you can check them out once.
