I hope this thread was written a little better!
So anyways, Coming to your question.
It totally depends on you and your usage as well, If you are really familiar with Windows Enviroment you should maybe stick to it, But if you wish to switch to linux and learn that would be totally over you. but alot of things work more better on linux if it's supported because as @
tryp4vps said, linux conmuses less resources than Windows. You can get Linux VPS much cheaper than Windows, Because some hosting idk requires you to have a licence or anything.
For me, It has always been VPS for hosting and Windows for Gaming. Game servers work soo much better on Linux!
My vote goes for Linux all the way!
