I am not going to go onr side or the other here but I will inject a little information I gathered from my nose.
In the past I have worked as a tankerman on petroleum tankers and have had the opportunity to smell the various crude oils from around the Contentent (like fine wine I can tell you where they are from by the smell.) I have not smelt the tar sands though but can give you a pretty good guess as to what it is like.
Crude from the West (Alberta, BC, Alaska) smells like a book of matchs due to high sulfur content. Refineries which refine this product must change all the pipework in the refinery on a schedule of approximately 2 years due to the corrosive nature of it. As it is speculation I can only say that the tar sand oil is worse at the point of extraction, but after preliminary refinement it may be slightly better.
Newfoundland crude is the best. I smelt it for the first time and could not believe the smell of it. It smells very close to refined oil. Next time you add oil to the car, smell the oil and it is not far off.
Gulf crude it about half way between the two.
Hope this enlightens someone, somehow.
