If you live in an oppressive state that surveils your entire purchase history, using a SeedSigner is probably a better choice than ordering a commercial hardware wallet.

In nearly all other cases, I think it's preferable to use a commercial hardware wallet like the BitBox02. You don't have to worry about a potentially tampered device, the user experience is far easier, you have physical protection and you get potentially better access to features like miniscript.

One other issue I see with singlesig seedsigner usage is that you have to store the seed somewhere and keep it accessible at the same time. So most users I've talked to keep the seed very close and not really in a secure location. You can easily keep a BitBox on your desk and not worry about anyone getting access to it, as it comes with a secure element.
