On a super recent Intel CPU with BIG.little architecture, I believe 11 has better scheduling. One day when games start to make use for it, 11 has DirectStorage and I believe 10 doesn't?

If you have an ultrawide display, you might appreciate the start button in the middle.

And that's about all the pros of Windows 11. Now for the cons: They've greatly dumbed down the context menu, so now you have to click the "more options" or whatever button nearly every time. Also it's possible that they fixed it a already but when I tried 11 near launch, the context menu took about 2 seconds to appear. Zen 2 CPU, 32 GB of decent DDR4 and an NVMe boot drive so it should be snappy And it's Windows. I right click on EVERYTHING because I'm not used to the weird-ass non-unix console. Gimme right click -> 7-zip -> extract to (subfolder), not right click -> wait 2 seconds -> show more options -> 7-zip -> extract to (subfolder)

But overall, Windows 11 isn't all that different. There are some UI changes, but it's surviveable.
