I do not understand why anyone would want to do anything else.

You will find it difficult to find many other SFTP servers than
OpenSSH, but it's not a bad idea to try some different versions.
The newer the better, of course.

Also, you can build libssh2 with debug logging, and call
libssh2_trace(session, ~0); in order to get lots of debug output,
which among other things will show exactly what the server is
sending.
