Before going for dedicated server plans, keep one thing in mind. Dedicated server hosting plans are costly than shared and VPS hosting plans. When you own a website that gets fewer hits every day, shared hosting is enough. You need a dedicated hosting plan only when your website gets more visitors every day. Though dedicated server hosting is costly, you will get full control over your servers.
Being a shared hosting user, I don't have experience in dedicated hosting. Instead of focusing only on plans, I would strongly recommend you choose the hosting provider who is more reliable in terms of service and security. You can get the best plans from the branded players who are in the industry since long back. If you are happy with their plans and prices, give a try on them.
