I love linux, i am php laravel developer.
Why Linux is best because it's smooth and faster then other and also it's free. When i was in college. i usally use windows for development of my php project, but almost huge hang my system and not feed as developer.
But when i start my first job i use linux and it seems to great experience with it. i like so much to work with it. I think linux is beter for every developer and it helps to learn new commands that can use in live serve.
Thanks :)
