Yes, in Leopard, unified and non-unified windows are the same except 
for some minor differences in the toolbar metrics, which you 
found.  :)  The metric differences were left in for compatibility.

I don't think the HIG has any guidance about when to use one or the 
other on Leopard, so I suppose you can use whichever you think looks 
best for your app.
