As per my experience of using Linux for the last 2 years, Linux provides you with a really awesome experience! because it is an open source Operating system which is really easy to use. It supports both MySQL and PHP. The cost of Linux and its distributions is very less. sometimes you need to pay for some of its pay based versions. But its cost is not as high as compared to Windows. It is versatile and people can make changes in its coding as per their requirement.
It is chosen by the users who work with MySQL, PHP, Perl, and Python. It also provides various open source applications for website hosting like CMS, Forums etc.
