I keep my Bitcoin air gapped as I think it's safer than on Trezor that requires regular firmware updates.
A properly airgapped computer is safer than a hardware wallet connected to the internet.
The Trezor wallet is only for smaller amounts as quicker to sign a transaction. Yes I will buy another Trezor should it fail, but I like knowing the seed words and pass phrase also work on an air gapped Electrum wallet.
OK, good. I was worried that your intentions were to export your seed from Trezor and import it into an Electrum hot wallet. Electrum supports BIP-39 seed phrases and Electrum's native seed format, so you shouldn't have problems there. The only other software wallet I know of that supports both seed formats is Blue Wallet.
