Hi Nick, and welcome! I'd say that pretty much all Linux distros are fairly secure, at least in comparison to Windows. I think that "ease of use" is personally subjective... what's easy for others may not be easy for me (yeah, I'm taking about Gnome 3 Shell here!
). But anonymity is mostly what I stopped to comment on.... you did not mention the
Tails Linux distro, which is about the only Linux that touts anonymity as a "feature."
Yet, it should be remembered that there really is no complete anonymity on the Internet, not even with Tails Linux. Anyone interested in this should be sure to carefully read
their warning page.
I seem to find far too often that privacy and security is a trade off with convenience... and most people will choose convenience in spite of the risks. This is why so many people still use simple passwords, and re-use passwords among multiple sites or services. This is why so many people still have not put a "credit freeze" on their credit information with the major reporting bureaus, even though Equifax was one of the biggest breaches in U.S. history. This is like waiting for a car wreck before considering whether we should buy insurance. It makes me sad.
