hmm well:
http://www.7-zip.org/
<---------------------------------------------
Supported formats:
Unpacking only:
RAR, CAB, ISO, ARJ, LZH, CHM, MSI, WIM, Z, CPIO, RPM, DEB and NSIS
--------------------------------------------->

so it seems 7zip lacks support for creating new rar archives, but if i get
that right, unrar-free also lacks that support:

http://home.gna.org/unrar/


also interesting http://en.wikipedia.org/wiki/7z:
<-------------------------------------------------
Full support

These programs support both the creation of and adding files to 7z archives,
not just reading files in them.

[edit] Linux

    * Peazip
    * File Roller
    * Ark (GPL) (acts as a wrapper around p7zip)
    * p7zip (GPL)
    * Karchiver (GPL)
------------------------------------------------->


last but not least:

$ aptitude show p7zip-full | egrep -A 3 -w /usr/bin/7z
 * /usr/bin/7z
   not only does it handle 7z but also ZIP, Zip64, CAB, RAR, ARJ,
   GZIP, BZIP2, TAR, CPIO, RPM, ISO and DEB archives. 7z compression
   is 30-50% better than ZIP compression.

so with 7zip you get a lot more then "only" rar support.
