I would say 7zip. Sure, it's not really popular, but what does that mean?
Every package program I know supports it, like WinRAR, Izarc, UltimateZip and probably even WinZip then, although I can't tell because I haven't used it in ages.
There's no more hassle with it.
I would say RAR is a much less supported format because with the exception of WinRAR there's no other application with which you can create a RAR-package. This tells us that it is a corporate format, while 7z is open-source, and don't we love that?
I'm not sure if this makes enough sense, but at such a late/early hour (4am?) I don't really care anymore....
