Do you recommend having a "gpg.conf" file containing "TEXTMODE=OFF" or just omitting that file altogether?

"TEXTMODE=ON" is an old PGP 2.x command. It has nothing to do with GPG. Plus, it's actually the opposite of what you want. In OpenPGP, a text file is canonicalized into a standard format when encrypted, and re-canonicalized to the platform local format when decrypted.
Both of these steps can change the CRLF line ending.
If you want to guarantee that there are no changes at all, and the decrypted data is a byte for byte copy of the original, then turn off textmode.
