Obviously, this depends on your environment. Some hosters, web servers,
applications may directly support one interface and not others.

If you control your whole environment, I would look for a newer
approach. I do not know "SCGI" but I know that "WSGI" is fairly recent.
This means that during its design, "FastCGI" was already known and
not deemed to be sufficient. Thus, you can expect more features
(more modularisation, in this case) in "WSGI".
