Yes, I saw this comparison. The difference is only in the use value.
The hardware differences interest me. As far as I can see, both solutions use the same EAL6-certified secure element, so it seems it's just a matter of software.
I think hardware aka java cards they are using are identical, but difference is the code firmware they are loaded with.
Take this with reserve and better contact Tibu directly or someone else from Satochip if you want to have official confirmation.
All I know is that you can use supported blank cards and make it into DIY Saochip, Satodime or Seedkeeper.
