I own wallets from both outfits, and it's my opinion that both are among the best hardware wallets currently available.
I know that Andreas A. owns both a Coldcard and a Ledger device. In one of his recent videos where he discussed the Ledger Recover feature with Jameson Lopp, he said he will continue using both hardware devices, but for different storage needs. It would be off-topic to discuss that here, but it's just something that I remembered now.
