Yes, very often. Due to some changes in code of mkmgap (I had written 
about this earlier) the draw priority compared to non mkgmap maps, or 
older mkgmap maps (before rev 10??) will always show in front (at least 
on vista hcx).
So mkgmap maps will usually always show in front.
However it might be that maps in the back take preference for routing 
(this is a black book on which map is chosen for routing, so if people 
don't deactivate (deactivating however does not completely deactivate, 
i.e. POI search, but to avoid routing should be enough) all other maps, 
they might be chosen for routing.
That's the same with routable basemap. So I am sure that if you have 
mkgmap produced europe.osm and route from say germany to spain, routing 
will usually be carried out on routable basemap, while short distances 
use europe.osm.
