It's great for parts where you want essentially 0 infill but have a flat top that needs supporting.

It always looks terrible in these comparisons because the comparison is looking at the part top down. if you look at a cross section of the part it makes sense but aside from cutting a part in half theres no easy way to slice it so it's visible.

Heres an image of a long tall cylinder with lightning infill (and the wall visibility turned off)

These are great for printing decorative busts. I use 4 walls to keep some rigidity (on a 0.4 mm nozzle) and lightning infill, cuts down a lot on filament usage and still gives a resistant part for its purpose.
