Go with the hobby, they did a real slipshod job on the retail but the hobby gets you 1 SP a pack and sometimes 2 autos. They SP'd Crosby, but they didn't SP Ovechkin, so if you hit Crosby you can pretty much finish the auto set.
I tried to get a Crosby auto last year, but it passed $230 and I let it go. Kind of regret that one now.
Also in the hobby case you get one of those crazy 8 jersey cards, retail you probably don't.
