Didn't you just make a thread and ask for it to be deleted? Anyways, get both, well worth picking up the complete package.
You should take a look at the gameplay videos and decide if you would want both. I had one then got curious and bought the other. And then I ended up deleting them both and buying "smiles" because I didn't want 2 icons taking up space. I can't decide which I like better. Zen and Drop serve different moods.
