Can Windows 10 be the sure replacement of Windows 8 or Windows 8.1 ? If not, why?

If you don't like it you can simply revert back in the settings.

It is improving so its worth a try and if you like it you can use it as your permanent OS

It's a replacement, but that's a subjective statement. For some people, like myself, I wouldn't bother with Win10 just yet. I'd wait until all the bugs are out, and they clean up the way it handles a lot of protocols. For the majority of users, it can be hit and miss.

Realistically, Win10 is a highly subjective "upgrade" for most people. I'd say try it on a spare computer, or in a virtual machine, and give it a try that way.
