Protein Powder Vs Protein Drinks

I went to Sams Club i bought the Choclate Premiere Shakes. 

I buy the protein powder form. I researched and found Jay Robb to be the best out there. It comes in whey or egg protein, its the first ingredient. It comes in chocolate or vanilla, and easily mixable and it taste pretty good! Take a look for yourself. But I found it to be the best out there with less carbs, plus its good for your protein smoothies.
