well you still have tried only web based wallets , they are much prone to hack as private keys are not stored over server , in case of blockchain.info new webwallet it is even more worst as point of convenience.
I will suggest you to use desktop wallets like multibitHD , it is good IMO.
Also hardware wallets I really like. I wish more people would switch over, but a lot do not due to price. Ive tried Trezor, Keepkey, Ledger, and all 3 are great way's to keep coins.
Nothing touches hardware wallets on safty. Only one that arguably does is a unused paper wallet and that is if you don't use it.
They have their bugs too, I`d not put all my money in hardware wallets. They have online interface, and any online device is vulnerable.
Of course never put your entire holdings in one place.... but a good hardware wallet is much better then most hot wallets. Which hardware wallets have you tried out personally?
And it depends on what your doing. I'm sure you can link to some old story/article. But in reality I think Trezor would beat most hot wallets out there. And if your on a compromised machine.... then hardware wallet excels even more as it signs on device not computer.
Please find any CURRENT vulnerability on Trezor that does not require user being at fault.
I guess Trezor is cool isn't it?
