There are cases where even hardware wallet can be compromised when you put your seeds around. This totally depends on the awareness you have on how different types of wallets works and knowledge on how to secure it.
Hardware wallet is very transparent also paper wallet if it's not using most of the people. Exchange Wallet is relatively risk more than other 3 wallets. Exchange hacking is now big hype, because a lot of hacked just in this year. so we are little bit disappointed to use.
