PSA
Pros:
1. Market share
Cons:
1. Cheap looking holders that don't adequately protect the card. Red label is a poor color to complement a variety of cards. Holders are very thin and the card shakes around inside.
2. Buzz that dealers get preferential treatment when submitting cards. True or false, this is bad PR for PSA.
3. Buzz that they grade inconsistently. I've seen it 1st hand many times. To the point of being blatent.
4. No half grades
5. No sub-grading. Just negatives for stains and off-center.

Beckett
Pros:
1. Quality of the grade. They are consistently strict.
2. Sub-grades. I like to see the detail behind the grade.
3. Brand recognition
4. Best holder in the industry for preserving the card
5. Free population reports. Web based.
6. Guarantee to grade in certain time or its fre
Cons:
1. Price. They are just too high
2. Sub-branding their name with BCCG, BGS and BVG. I think the BCCG product is a disgrace and caters to TV shoppers and ultimately hurts the industry. I think they made another mistake by realizing too late that there is a difference between a vintage and modern card and then branding it such. This is all unnecessary. Use one brand name and be consistent.
3. Color of their labels. Their white label below a certain grade actually deters from the card. I think the bronze color is too dark. I think that if you want to color code at all you utilize silver and gold only. Maybe you find a different shade of metallic to throw in. If I kept the colors that they had, I would have put a 9 as gold. I would also put 7 to 8.5 in silver. Everything below should be a color that is more complementary to all cards.
4. No deals or incentives to incite me to use their product. Example: registry.

SGC:
Pros:
1. Price. Promotions & deals.
2. Customer Service. This forum and response from SGC personnel
3. Set Registry
4. Consistency of grading.
5. Half Grades
6. Under-valued cards allow collectors to buy quality and a better price
Cons:
1. No sub-grading. I admit that I like this extra information. I can generally figure it out myself, but this gives me the insight of the actual grader.
2. Inconsistency in the foam black holder. Sometimes there is a gap around the card. This gives me the impression that this insert is not applying consistent pressure, which leads me to believe that over time the edges could get damaged.

SCD
Pros:
1. Nice looking holders
2. Sub-grading
3. Half grades
4. Consistent grading
5. Recent price reductions.
Cons:
1. Association to Larry Fritsch. Having his son advertise with his own Mickey Mantle as if he is Mr. Common Collector is just a dumb marketing move.
2. That black foam insert. Just not sold on what this thing does to a card over time.

After stacking up these 4 big grading companies, I've decided to send my cards to SGC. I will buy from all companies except PSA.

Enjoy your collection!
