The Shopping Bag have more variety including blush/bronzer etc, so it's better if you want to play around or have a complete look.
The Smoky Studio is mostly eye/lip. BUT, you can take out/rearrange strips with set of 3 pots. If you are travelling, you can put together whatever combination of 9 things for a mini pallete.
So, shopping bag has more option, smoky studio is more flexible.
