pjmlp seems to be an expert in a lot of this stuff but I'll throw in one other perspective: if you need to write a native app on Windows, yes, UWP is the way to go, certainly over MVC, WinForms and WPF. But it is tied to Windows... I doubt the performance improvements are significantly different. It's really about portability (Windows Store) and latest Windows features (start menu, menu bar, Cortana, ink, touch, high dpi) Also, I hear if you do have an exiting WinForms/WPF app, you should be able to upgrade it to UWP.
