They are the same. The .rar I posted is a solid archive. It's much more efficient at packing, particularly with text-based files. The drawback to a solid archive is that one corrupt file can corrupt the entire archive. It also has to re-pack all its contents if you remove or add an item. In the past I had forgot to use this setting when packing the .rar download version, that's why the difference wasn't so much previously.
