For now i will choose bank. Because for daily use i used fiat for transaction and not many people using bitcoin. But maybe in the future when everybody use bitcoin i will choose using bitcoin.
if i had a chance i would definitely not use banks to be honest because bitcoin wallets are way better as they allow you to safely keep money
The safety of your wallet files depend on you, and not your wallet client. Its not that when you use a Bitcoin client that your holdings are secure. You are responsible for that. PC security, not downloading weird stuff, not visiting shady websites. All things you have to look out for when it comes to safety.
