Hi guys,
Many times people are confused which hosting shall they choose out of Windows and Unix. Below are some points which can help you in deciding.

1.UNIX is meant for the large network systems, while Windows is the need of individual users or companies that don't want to deal with the complexities of UNIX administration.

2.UNIX has been around, in one form or another, for the last twenty years and as such is a very mature platform. Because of this, the system is very well developed and stable, and there is a lot of software and applications designed to work for it. Windows, on the other hand, was created more recently by Microsoft as a system specifically designed to handle the user-friendly software, which it has developed for Web page design. With Windows, you get a platform that runs a series of naturally compatible programs and applications that mesh easily within the ubiquitous Windows environment. The main thing is to decide which system suits the projected needs of your Web site

In my eyes, unix all the way.
