Anything you stuff in RunOnce does just that, runs once and then what you stuffed removes itself.

Anything you stuff in Run, runs every time until you remove it. It does not remove itself.

So, if you need to do something that needs to run after the logon script, but you want to initiate it from the logon, you stuff RunOnce during every logon. If under changing circumstances, you no longer need the post-logon script, you simply stop stuffing RunOnce.

I would think this to be preferential to stuffing Run, as you have finer control over it. FE, if you stuffed Run with a call to a script that needed to access a network share, and the user ran islanded (laptop or whatever) the share would not be accessible and it would error out.

All this, however depends on individual circumstance.

Marcilly,
Hope this helps. Sorry for the long dissertation. If you already know all this, sorry X 2. Now, back to the exam!
