I see you've made your decision but i'll just reiterate what others have already said, buy what you think presents the best for what you collect. Some collectors go for page quality over centering, others go for a better wrap over page quality. Me personally, I've seen 4.0's with lower page qualiy that present better encased than 8.0's that are miswrapped with better page quality. At the end of the day, it's your collection so buy what you would be most happiest with. Resale value is another conversation.
