The sheer number of times I've had issues with Windows drivers is anecdotal, but consider carefully. I've had impossible to boot systems because the network driver isn't included in the core installation media. I've had video cards not work out of the box and require me to install massively bloated control centers to use. And the number of complaints from unexpected reboots? And that's in a pretty standardized computer lab, trying to make my Grandma's computer use the correct resolution on her monitor was literally impossible.

I guess it depends on how you define laymen? I think Ubuntu worked out of the box with everything I've thrown at it in years.
