I am a FFS fan. Its offerings in range cards, offsets wind vales for that range cards, LRF card generation and zero to ELR curves are not matched.
But it is worth acknowledging, that just like we sometimes point out deficiencies in other programs, that that does NOT matter to some shooting disciplines. The way that the current ELR stuff is being shot F-class like; the solvers have less value, because the FFP is always the same, the targets in a narrow band of distance the curves are tuned in that narrow range. Many of these guys don't seem to care if their gun zeros at 100 or are dead on all the way to the end. They may not even know the curve they just developed for 2500 doesn't work well at 500..
Just worth saying~
