I'd like to see some specifics somewhere. For me both are crap and I don't see a reason to move from Win7 but some software is now forcing me from it to perhaps towards Linux if it will work there.
Just try it yourself. Hopefully it works for you.
Folders don't always open. Have to press windows key.
Start menu doesn't always open. Have to press windows key for it to respond.
Need to restart Explorer often as something gets stuck somewhere in UI.
Settings are all over the place.
Audio settings are mess.
Doesn't recognise my microphone of headphones. Have to open realtek setting and go to advanced setting and then tell it that it is a headphone with microphone.
Stuff are hidden behind menus inside menus inside menus.
Folded View settings doesn't stay and have to keep on telling the stupid thing not to group it.
MS wants to push suggested apps and promotions.
Windows key + P doesn't always work properly with multiple displays.
Right click menu requires more actions to use some functions.
There are a 100 other small things that grinds my gears and I'm not gonna bother listing it.
