Thoughts on : Yubikey, Trezor, stamps.com'ish BTC Services, HD Wallets

Just wondering...am I wrong in assuming -

Yubikey 4 - secure and dope as fuck

Trezor - secure

Stamps.com... - probably a honeypot or at the very least extremey risky

HD Wallets - Cool but probably a chance someone can extrapolate all of your wallet address from one single address, possibly a need to scrap them after (each?) multiple uses?

Bonus : If you have a regular wallet, lets say a cold storage wallet you printed out with entropy or something like that, can you take the long ass key and convert it to the 12 words? Are the 12 words a "one way" thing?
