Frustration free as Windows? You're kidding, right?
I recently showed a client of mine how Ubuntu works out of the box. No hours of rebooting, no ads in any menus, no online account requirement, no persistent anti-malware scanning, no UI elements from the 90s showing through. Drivers can be an issue, power usage perhaps, maybe sleep is annoying (especially on shit hardware) on laptops but apart from that I don't know how you can even compare the frustration from a recent Windows system with a modern Linux desktop.
