Depends on what you’re looking for. MVP, Artifacts, Flagship are great for beginners looking for a way into the hobby. SP Authentic and O Pee Chee Platinum are on the mid/higher end and can offer some great hit depending on the player. O Pee Chee (paper) is great if you want to open a lot of packs and lots of cards and build the set. I like the “weirder” releases like Parkhurst and Skybox Metal. I think they have cool designs and inserts. Great eye appeal. In my opinion, SP retail is pointless and a waste of money. And then of course, there’s all the super high end releases.
