i would choose bitcoin wallet because i don't really trust banks, because there are lots of stories when banks didn't give you your money, money that you store in banks, while nobody will stop you from using your money in bitcoin wallet, also storing bitcoins in wallet can give you lots of profit after bitcoin price rise
Banks pays you interest on regular interval, and in bitcoin you need to continuously make efforts to grow it, bitcoin wallets are safe no doubt about that, but banks are also necessary for day to day transactions.
