Use Noise Ninja in Aperture or Photoshop?

Question

If I am going to edit an image in Photoshop (eg cloning some clutter out) and want to reduce noise, is it better to do this in Aperture with Noise Ninja and then edit with Photoshop or just send to Photoshop apply Noise Ninja and then make other edits?  Is this an option, does Aperture send the Noise Ninja edits across to Photoshop or are these lost?
I am moving to CS6 and will run 64 bit (and Noise Ninja for Mac is still 32 bit ... annoying).  Hence my interest in running NN in Aperture.
Of course if Aperture or Photoshop matched NN ...

Very good reasons  .
OP -- do you need to use an external editor for any other edits?  If so, then use PS as the base file for all external edits.  If not ... imho it's easier (and this ease if worth something) to just launch the external editor directly from Aperture.
So _if_ you are going to edit in PS, _and_ you are going to use NN, then call NN from PS.
Put generally, I suggest that you _always_ launch external editors from PS whenever you will be using more than one.  This aggregates the edits into layers (at least I think it does) saved as a single Aperture Master.  (Each calling of an external editor creates a new Master in Aperture.)
Aside: the handling of externally edited files in Aperture violates the "non-destructive workflow".  The implemention is, imho, immature.  I'm hoping for a robust solution in the next full release of Aperture.
