OpenPGP or S/MIME?

3DES is the default cipher (encryption method).
You can check it here:
Kleopatra settings -> GnuPG Systems -> GPG for S/MIME -> last input field
$ gpgconf --list-options gpgsm

For OpenPGP there is no default cipher; it would be set by the preferences of 
each OpenPGP key. 3DES is a fallback which every OpenPGP implementation has 
to support. "gpg2 --version" shows which ciphers OpenPGP supports.
To show the preferences of a special key:
$ gpg2 --edit <keyID>
> showpref
AES256 should be default if key is created with current GnuPG.
I'm currently not sure if and how can you change this. Maybe some GnuPG 
experts can help you.
