Don't over-think it. Unless there's some particular thing that only a certain operating system can run/do then there's really not much difference. People just have that inherent need to rationalize everything they do, so they will be saying how they're using this or that system because it's faster, more stable or whatever else. When in fact the biggest reason is that simply they are used to it.

I'm a Windows guy and couldn't care less to switch. I don't know where those crazy stories of Windows crashing everyday etc. come from. An OS just like all the rest, if you have to actively look for a reason to switch then there's probably none.

But still sometimes perhaps it's nice to just change the environment. Makes life more interesting.
