Granular role permissions to backend menus / areas?

I would like to restrict one of my users in the backend area. I would like to give them access between editor and administrator. Is there a recommended way to do this?

I found this plugin that can give granular control:

I am not sure how safe this is especially in an MU setup or mixed with other WPMUDev plugins.

Here is an extra discussion about this in the WordPress forums:

Any input on this? I would appreciate help or advice.
