Qubes OS: A reasonably secure operating system

openbsd vs qubes os, which one will you prefer?

As an OpenBSD fan: consider Qubes instead if you want a "desktop" experience. OpenBSD works fine, but the open-source desktop is quite vulnerable (consider how many things need to go wrong for https://scarybeastsecurity.blogspot.nl/2016/12/redux-comprom...), and a lot of OpenBSD's hardening is in the (simpler) base system, not in GNOME / KDE / Firefox / Chrome / ...

Alternatively, consider not running a full-blown desktop or using Windows, which has grown a lot more secure since the Windows XP pre-SP2 days.

Are openbsd and qubes really comparable?

QubesOS -> Secure Desktop

OpenBSD -> Secure & minimal Server

OpenBSD doesn't have the isolation and hardening on the desktop apps, as Qubes has.

To a certain degree. If you're unfamiliar with OpenBSD, security is basically its #1 priority and it's often recommended when you want better security on your server

Wow, your recommendation for desktop security is either not running a full-blown desktop or running Windows? As in, Windows beats the popular Linux distros in desktop security?

I run both -- but which I'm using at a particular time depends on the particular use case.

For this article's target audience, Qubes OS is the better choice.
