Personally, I really enjoyed the two-parter. There is just something about these two going head up that I like. I liked the earlier clash when Priest did it in Deathstroke and I even liked the God-Killer fight in New 52.
I also thought the angle of Lois' story was really at the heart of Deathstroke too. Good couple of filler issues, imo.
Here is what I'm talking about for people catching up:
