It works pretty well for greenfield projects on .NET, so long as you can live without third-party libraries that don't support AOT.

Existing code bases can be a pain, though, especially applications that heavily rely on things like C++/CLI and COM Interop that basically need to be rewritten from scratch.

Which is not to say that it's intended to replace the traditional JIT runtime in applications where it isn't troublesome, because it's not.
