The slightly smaller sizes of 7-zip and RAR is false economy.
The RAR format is one of those things that would put a smile on my face if it was dead and forgotten. It's a proprietary format. It's slow. WinRAR sucks at creating and unpacking RAR files - other programs that can create and unpack from/to the RAR format outperform WinRAR in terms of speed at identical compression.
Not so with 7-Zip. It has a safe and free license. The only issue you might have is that Windows doesn't support it out of the box (or didn't, last time I checked), but this is a non-issue as unpacking 7z files is handled by GH using 7za.exe.

Finding, downloading, installing, then learning a new application takes a lot longer than the extra download time of a ZIP.
Yes, but GH ships with 7za.exe so no need finding it.
As for the full 7-Zip program (or any other programs that support the 7-Zip format) installing it and learning to use it is a one-time thing, only applies the first time round, and that will happen sooner or later.
7-Zip's compression ratio to ZIP can be high, even half the size (depending on the content) which is a lot when you think of downloading an 18MB GTA2 archive on a slow connection (but fast enough for GTA2) vs a 36MB one. Makes a difference when you want to download a whole map pack.

On top of that, you have to put up with the clutter they all add to context menus and other UI.
You don't have to.

Peole who don't like the 7-zip GUI are forced to use it for .7z files?
No they're not, there are many alternatives, and as mentioned in the first point, GH does all that for you.
