How is seeing sjlj great? It is the by far most inferior way of exception handling, on any architecture.

The only advantage of sjlj over dw2 (solely under Win32) is that it works with exceptions that take a weird way through system DLLs, which really isn't an advantage if you ask me (shouldn't happen in the first place). And in respect of vectored exception handling, it has no advantage at all.
