At work we use RHEL, so thats why I was looking at CentOS. The main reason I am going to switch to Linux is to improve my own skills and get experience with it.
I installed Manjaro this morning and I really like it, nice and clean and I will use it as a base for the time being.
Fedora.
Although they've made a few bizarre design decisions. Like.... getting rid of desktop icons.
Supposedly it is a Gnome decision and will eventually affect all Gnome based distros.
Also apps don't seem to have a minimize button....
I'm not selling it to you am I.
I was a Ubuntu user, but I found 18.04 a bit buggy and I don't like the Ubuntu colour scheme.

I found the minimize. It's in the right click menu of an open app.
