From personal experience, 11 can't do vertical taskbars and the hack that restores 10's taskbar isn't entirely bug-free and can be shut down on a whim by MS with an update removing the functionality.

From what I've read, 11 is a privacy nightmare with Recall and the ever-worsening insistence on having a fucking MS account to log in to your PC locally. Sorry I meant your self-serve surveilance and ad-targeting appliance.

Having to fight the anti-features and dumbing down of a piece of hardware you supposedly own to keep it usable and useful to you, not the mothership, with hacks of varying reliability... What part of that sounds like something you would want to spend any of your money or time on?
