Not better, in fact it's worse.

A hw wallet like cold card can operate air-gapped.

You can use Bluewallet to watch all your wallets on your Coldcard. Using BIP85 on the Coldcard makes the need to backup all your wallets' keys redundant.

I highly recommend a Coldcard instead of a mobile phone. Don't forget that the battery on a mobile phone has a limited lifespan.
