Comparison with admin/developer?
What are the perms compared to both Developer & Admin?
The plugin provides what is shown on the plugin page: https://umod.org/plugins/faux-admin#overview

Anything that Rust checks against the IsAdmin / IsDeveloper flags would work with this.

But, if you are asking if there is a difference if you set IsAdmin vs IsDeveloper to be a FauxAdmin, there is no difference in what users can do via this plugin.

The option is only there to give option either/or.  Some plugins use the player flag IsAdmin to do there permission checks, so I added the IsDeveloper to give alertnate flag for player, but still give same FauxAdmin "Powers"
