I’m going off a sample size of exactly 1 but I have to believe that CGC is grading Restored books much more harshly than unrestored, whether they admit it or not. I recently submitted 2 copies of JIM #112, one of which I had posted here. Superficially one copy was far superior, no question, and I submitted that one in High Value. The other was a nice mid-grade plus copy.
Results: High Value copy returned in a Restored grade 6.0 (sidebar - I was taken by KellysSuperheroes on EBay - avoid at all costs!)
Vintage tier copy returned Universal grade 7.0
if you were just judging the 2 without knowing of restoration 100% of people would say the Restored copy looked superior.
I have a 6.0 of your book, yours looks slightly better, I would have said 6.5-7.0.
