This is my standpoint with wallets. I am that kind of person that does not like anything all in one basket. I currently have 4 but the reason for that is some wallets do not support other altcoins like litecoin and dogecoin.  I also feel it is just a bit safer - if something is going wrong with one wallet - which we have seen - then I can quickly transfer to an already established one.  Coinbase is my main man for Bitcoin, feel safest with them.
