When I buy one, I'll invest in the one that monitors sleep since sleep hygiene is a problem for me. If quality and/or quantity of sleep is an issue for you, then the additional cost might be worth it.

I have the FitBit One, and I love it. I don't use it to track my sleep (after the first couple of nights), because I don't feel like it gives me all that much information. I haven't seen the size of the Zip, but I think the One is about perfect.
