It's true, if you can't secure your device, seeds, and private keys then no machine is secure. Even on Electrum, there was a hack attempt a few months back. If you are wondering to handle a big amount then it's strongly advisable to move into a hardware wallet. You can use Electrum with 2FA but you need to spend a few extra fees. I wouldn't recommend paper wallets for various reasons especially change address issues. Keep in mind, you have to secure your device and wallet credentials to secure your funds.
