Version 3 is foil lined. Version 4 is a longer collapsible
model.

Not noticeably. In both cases the angle of coverage of the flash is such that it just fills the front panel of the softbox so there is no light spillage there. I would think that any light reflected off the front panel is going to be pretty much lost anyway and even with a foil lined tube you wouldn't get much back out the front. With the longer one, I did go with tissue paper which greatly reduces the amount of light reflected of the front. Anyway, I am getting sufficient light out of each of them.
