Stanton, Posey and Kershaw aren't in 2008 Bowman Chrome, they're in 2008 Bowman Draft, which is a far more expensive product. The best autograph in 2008 Bowman Chrome is Jordan Zimmermann.
2008 SP Authentic has some good stuff, but quite a lot of it is redemptions too, which will be long expired by now. Kershaw, Carlos Gonzalez and Scherzer were all redemptions, so pulling any of those is a wasted hit. Votto and Longoria are your best bets. Lots of the guys in the product are long since out of the league.
Not trying to be mean, but those products are discounted for a reason, and I think there might be more interesting things to get for that money. If you're definitely getting one of the two, go with the SPA.

Trading for cut autos of baseball HOFers I don't have, autos of current and future Cleveland Guardians, and anything else that catches my eye!
