I can see the benefit of them, but it shouldn't be a determining factor when buying a new set of screwdrivers.
IMO, I'd only get a flat head with a striking cap...but I'd dedicate that as a small, handy pry bar; not as a screwdriver.
If you already have all the general assortment of screwdrivers, then I'd think about purchasing a few select ones, but I'd only opt to strike the cap in the event that I can't gain access to/or don't have space to operate an impact screwdriver.
But....I actually have a pair of P2, and P3 Swiss Grips with striking caps just cuz they are pretty.
