I have seen cars with the carb both before and after the turbos. Both seem to work just fine, the draw through one I saw in person is even daily driven.

I was wondering if anyone had any ideas on the advantages/disadvantages of both?

Carbed blow-through is old school. Carbed draw-through is WAY old school. Go with a blow-through setup. Shorter, more accurate path from the carb to the combustion chamber. Better fuel distribution. We only ran carbed draw-through turbos on our Funny Bikes...
