so my question is... Are there any other reasons that you might choose one exclusively over the other?

My work involves a single web server supporting many clients as virtual hosts, each running an individual installation of the same application. Between them, the clients are running several different versions of the application, and I therefore cannot use mod_perl v1 because it won't (as I understand it) cope with the need to distinguish between multiple versions of the same module.

I believe that mod_perl v2 incorporates a solution for this, but I haven't yet had time to investigate that. For now, it all runs with CGI.
