SUA with Manual Sandbox set to "Limited": any benefits.


I have started using in the past few days the SUA in windows 7.
Is there are any real benefits in terms of security, by choosing “limited” instead of “partial limited” in the Manual Sandbox.
For example in Sandboxie there aren´t big benefits if one chooses “Drop rights” in a SUA.


P.S.- I have already seen the Help file, but was unable to make a conclusion.
