I've been doing some research into air-gapped cold storage methods and have found some options
Are there other well adopted methods with best in class security for cold storage, not only for bitcoin, but other cryptocurrencies as well (ethereum, zcash, etc.)? What do you prefer?

Creating a offline wallet on a live Linux cd. You would create the wallet just like you would on your personal computer but on a clean bootable live cd like Ubuntu offers. This option is good if you are not going to be accessing this wallet for a long period of time. Of course you can access it via the offline Ubuntu live cd if you wanted too. But, anything other than that could compromise it.

I'm not familiar with the options you have provided in your original message, except for tails. Tails is a very similar process to the one above.

I use Bitkey for my long-term storages. It's as easy as downloading and flashing the image in a flash drive, so the regular user won't have any problems with creating a safe environment without having to sacrifice their safety for convenience.

I imagine that you could download several tools for other altcoins - like MyEtherWallet - and use it in the same offline device along with the traditional Electrum wallet for BTC.

Hardware wallet

Hardware wallets are great but not the best. I want to find the most secure solutions.
Here is an example linked to from the bitkey website:
https://www.turnkeylinux.org/blog/secure-bitcoin-transactions#comment-20749
WHEN USED IN THE RIGHT WAY BITKEY CAN PROVIDE BETTER SECURITY THAN TREZOR.
Don't get me wrong, I'm not saying Trezor is worthless. Once it comes out Trezor is going to be a great addition to the Bitcoin toolbox.
However, for high value wallets, I'd much prefer a solution that unlikeTrezor:
Allows you to use it in a way that doesn't require you to trust it at all.
Built from generic widely available standardized hardware like the PC (or better yet the Rasbperry Pi).
Doesn't require you to connect it via USB to a potentially hostile computer:
Frankly, as convenient as it might be, a USB interface for a device with that kind of risk model is very unwise. Especially for people with high value wallets, which would presumably be the first in line to use Trezor. An optical channel based on QRcodes or better yet OCR of human readable text would be much more secure.
That's the idea behind BitKey. The solution we wanted didn't exist so we created it ourselves.
