Tails should not be in this list. It is a single purpose tool/distro that is one of a kind unless you make your own with the same features. If you want security Tails is pretty hard to beat, and it is easy to install and use.
Comes with the TOR browser and all encrypted environment that losses all memory of what you did and it is an isolated system from your machine. It is in a class of it’s own for what it does for you.
It is a very secure browsing tool rather than a desktop environment distro. And it works very well for what it was designed to do.
