What's the point in trying all these different distros?
They're all fundamentally the same, you won't get a job for experience in installing every distro. Instead of thinking the grass is greener with some other distro, learn whatever you've got installed now inside out, try and learn the minutiae of Linux in detail. That
will get you a job, and also develop your knowledge of computing. Trying every distro under the Sun is just a waste of time IMO.
Not having a go, just does my head coming into the Linux forum and it being populated with just page after page of "What distro?".
