I changed from trezor to coldcard. I found that the coldcard was a fair bit harder to set up. I think it probably took me 5-6 hours to organise it (I am a little retarded), which was pretty frustrating. Now that it's set up though, I fucking love it. Learnt a fair bit through the process.

My general feel is that trezor is optimised for UX, where coldcard is optimised for security, which was ultimately my reason for changing.
