In my opinion, yes.
I am completely with you on Pokemon Shuffle, I find it somewhat boring and frustrating. But with Pokemon Rumble World, I have been addicted to "catching them all" ever since I downloaded it. Plus, after you collect the first 11 species of Pokemon, you always have something to do regardless of the situation. You have many fun things to do, and the Pokemon all get awesome looks way better than the flat Pokemon from Shuffle. I believe if you download Pokemon Rumble World you will enjoy it.
