7-zip, like most zip programs encryption doesn't even come close
to the level of protection that you are getting with GnuPG. Even
if you are using the lowest level cipher GnuPG provides, it is a
quantum leap over the zip programs enciphering. Quoting from
the man page for zip (roughly comparable to 7-zip and probably
uses the exact same code for enciphering):
(And where security is truly important, use strong
encryption such as Pretty Good Privacy instead of the
relatively weak encryption provided by standard zipfile
utilities.)
When encrypting to a *.7z file, 7-zip uses AES-256 in CBC mode, with a
passphrase-to-key function based on SHA-256. This is actually stronger
than most cipher preferences on OpenPGP keys. It is not the same as
the weak "winZip"-derived encryption. Of course, these files can only
be read by 7-zip, but it is free and open source. (It also compresses
a lot better than standard ZIP's DEFLATE algoritm, if more slowly).
