I've done a very quick and dirty count of the "votes" so far on holes Vs studs.
In some messages it's a little difficult to determine exactly which method is preferred but I very roughly divided them into three categories:
Holes preferred
Studs preferred
Either way is fine
The results:
Holes 21
Studs 5
Either 10
So far, holes would seem to have it. Not that this means all that much, it really is a personal preference thing I think.
