> The start menu in 10 is a lot more customizable vs. Windows 7 which I think is a good thing.

I installed Open-Shell day 1 when I got Windows 8, and continued with that on 10, since the new start menu did not convince me, so I can't really vouch for that. I don't see a need in having tiles and such in my start menu.

> Task View (virtual desktops) were added in 10.

Never used it in Windows. On my Mac I use it to put individual apps in full-screen, so they're easy to switch to with 3-finger swipe. Then again, I have three screens, so the demand for more desktop space is close to zero on what would be my Windows machine.

> Task Manager is so much better, that one is probably objective.

Technically a Windows 8 addition, but I'll give you that one. I'll have the old task manager back if I could get the old photo viewer back though. I can manage with the old task manager. I couldn't manager with the Win10 Photo app, and had to install Irfanview to get a usable picture viewer (at least before I went to Linux).
