Of these I used all but Zortech. None of them compare to GCC6. I've also used Microsoft C++ compiler fairly recently. It's not even close. I don't use Xcode when coding C++ on OS X, vim + YouCompleteMe beats the heck of any IDE I have ever used. I prefer Linux "perf" to Instruments, too. It's not an option on the Mac, but if it was, that's what I'd be using.
That's the first time I've seen a VS user praise MSBuild, which is utter garbage. On the unix side you won't hear much praise for GDB or LLDB, but for everything you've listed numerous tools exist. Eclipse in particular has superior code indexing/navigation capabilities. Both QT and GTK have GUI builders. NVidia provides a plugin to debug and profile GPU code.
What Microsoft compiler doesn't provide in my experience is decent codegen.

Not when compared with the enterprise and ultimate versions.
Or with the changes done in VS 2015, improved in the upcoming VS 2017 for incremental building and database storage of symbols.

Miles behind of what Blend + XAML allow for.

How well does it work with Intel and AMD cards?

On Windows, among commercial compilers, only ICC generates better code.
