Well, Linux definitely sucks.

By a chance - is there anything better? Pretty please?..

Actually in case Fuchsia manages to replace - well, I would be happy. But would it really happen?..

Windows

Sorry, but what is "Windows"?

Nice little OS, has been around for a bit. Good backwards compatibility to boot.

I had a look at it, looks like another inconsistent pile of unsafe C crap stirred with tons of legacy frameworks and complete incoherence.

Doesn't look like an OS at all.

Windows is a mix of legacy C code, which started to be migrated into C++ around the Vista time (hence /kernel in VC++) and .NET/COM (WinRT is basically COM with some extras).

Modern kernel code makes use of WIL.
