If you use a strong passphrase, the two are equivalent from a security perspective, since hw wallets also allow passphrases.

A piece of paper is easier to hide than a hardware wallet, but physical possession -- or even momentary appearance on camera -- compromises it, minus any passphrase, whereas a hardware wallet is robust to those things -- you have to defeat the PIN before you can even start on the passphrase.

I suppose SeedSigner could be cheaper, but it's certainly not easier, unless you're using some weird definition of 'easier'.
