it really depends on what you are planning on doing with the bitcoin:

if you are new to bitcoin and dont really know much about wallets and how they work: go to coinbase.com
if you just want to store it and dont plan on spending anytime soon : get a paper wallet from bitaddress.org
if you plan on doing alot of transactions everyday to multiple users: get electrum wallet for pc
if you spend and receive money occasionally : get mycelium for android, (if you have an apple device: get bither)
