I have a Costco card, too, but I like Sams Club for their cake decoration options because I have 3 kids and I love the taste of their chocolate cake, decoration choices (frosting is just right for me, not too much and not too sweet like other places, you can have a picture put on for no extra charge, comparable price/servings) and I like it for their toy selection come Christmas. Also, love that their gas is unbeatable vs Costco vs Arco, too...so worth it! But on the con side, don't like how when you exit, the checker gives you a distrustful vibe as they compare your cart against your receipt. that could be improved upon.
