Neither really.  The application itself contains no user specific files 
so to me, it doesn't matter.  Are there any specific reasons why you'd 
want one over the over?

My major concern was to remove the Installshield version which I now 
know is per-machine.

You could certainly do this; it would avoid the need for a bootstrapper. 
 You'd basically set a launchcondition to look for the old product.  
This would work reasonably well if you were forcing ALLUSERS to a 
particular value and it didn't match the existing product's value of 
ALLUSERS.

Are you trying to force per-machine or per-user or are you letting the 
user choose?
