With a DIY solution like SeedSigner you are not trusting the hardware, the data is stored temporarly on RAM and wiped when you plug the cable off. Its completely different from an hardware wallet that stores data inside permanently.
Maybe if you bring your own entropy, I haven't gone through the seedsigner docs but I do like that it's commodity hardware.
I'm convinced most hww are Intel agency honeypots and would never use one in a 1:1
