The Task Manager that many times also stopped responding or was permanently stuck behind a frozen full screen game?
On Linux, KDE has the plasma System Monitor, and if you can't use it for some reason you can switch your entire session to a TTY with CTRL+ALT+F2 and kill any process you want.

How intuitive. That's often disabled, and I've definitely had machines that were so frozen even that didn't work. I guess sysrq keys might have worked but if you're seriously going to suggest that you haven't understood the problem.

Hasn't happened once for me for as long as I can remember.
In fairness Linux has been pretty solid for me too after upgrading to 128GB of RAM and 64GB of swap. But I never needed to do that on Windows.
