I just added a super to one on my hives. I had 5 frames of drawn comb from last year that I put in the hive along with 5 frames of just wax foundation. Well there's no contest really. The drawn comb is about half full of capped honey and the blank foundation is only about 20% drawn out. I think the outcome of this little experiment is that drawn comb is worth it's weight in gold(en honey). So, don't throw away comb; do what you can to save it.
