TPMs are perfect for IoT devices, but I don’t see the appeal for one’s personal computer.
Regardless of platform & OS, full disk encryption for commercial reasons when necessary, but not for personal reasons including laptops. Instead for personal bank data etc., use spot/file encryption.
Whole disk encryption using the TPM keys. If you decide to donate the disk to a charity, they will not be able to read your data. They will be able to wipe the disk contents and replace with their own.
