Contrarian take - Ledger is more secure than Coldcard.
There are no guarantees than the open-source is actually compiled on a the MCU chip.
The chip secuity infrastucture of BitBox might be the best, but I just don’t like it and it feels like there are some unknown risks of combining both MCU & secure chip for unlocking seed.
PS. I use Coldcard because of air gap, but might switch back. The only thing I hate is that there is no #Bitcoin only Ledger :/
