Which Seaver RC would you keep?

[Metsfan0507]

I currently have 2 Seaver rookies: an SGC5 and a PSA8(MC) and I'm looking to get some opinions on which to keep long term. The 2 options are attached, but to summarize my thoughts:
1. The SGC5 seems to have slightly better color and much better centering (although still not perfect), but has some print spots
2. The PSA8(MC) has no print spots and much sharper corners, especially evident when looking at the back
3. Edges seem to be about the same on both cards
4. While the PSA8(MC) obviously has terrible centering, the card isn't missing any of the yellow background on the front, and the green boarder is present all the way around the back.

My understanding is that the (MC) is generally worth approximately -2 grade points, so the PSA8(MC) is essentially a 6. Is that correct? Or does the terrible centering take away from the card so much that a typical collector would actually prefer the SGC5?
