I would definitely prefer Friday’s off. I have found that more events happen on Thursday and Friday than on Sunday and Monday. But in the end, I guess I would prefer either. Any break is nice. 
The way they do 10’s around here, you have to work M-T-W-T and have Friday off, weekend off, Monday off, then work T-W-T-F, weekend off, M-T-W-T again.
I work 9-80’s and have every other Friday off. I like Fridays off better than Mondays. It feels more “weekend-y”.
