Hi Robert:
 
Yes 7Zip compresses sometimes (most of the times) more than WinRAR. In fact as far as I
know they both use the same algorithm for text compression. 7Zip has 3 compression
algorithms so you could try all and see for yourself. It also supports streams so you can
compress things from the output of one of the algorithms and make it the input of the
other. For example to compress executables you could use jcc and it´s output pass it to
LZMA. It also provides larger dictionaries if you want. WinRAR´s maximun size is 4 MB so
usually WinRaR files are larger. When it comes about speed WinRAR is faster. But I guess
that´s irrelevant right now. On the other side I think that sourceforge someday should be
enhanced to give users the option to download the files in the selected format, maybe
providing a link to the decompressor. Maybe I fill someday the feature request form for
sourceforge It will save us and maybe will save them some time.
 
Best Regards
Waldo

Having read your comments, I came to this conclusion:

I'll have a try with 7zip and if it compresses slightly less or better
than rar, I'll use 7zip (because it is free). For a test period I'll
provide both, zip and 7zip/rar and the user may decide which one will
win. Additionally I'll provide a file 'how to decompress.txt' in every
release. Wheras I think, people who come to download an OS know enough
to find one theirselves.  Making exe-files is still an option but I
don't like it. So you have to convince me.
