in my opinion these are our top tier lists:
first, Blisterskin Royal Mordants. Probably with one terrorgheist, as is our best way to do mortals, but recently Bill Souza played a list in a local tournament without terror , playing an unit of 40 ghouls, 9 flyers, 9 horror (hollowmourne with the crypt infernal as general) i guess that's a way to don't instalose if we lose our terror against shooting armys. But i prefer the classic mordants with terror, archregent, varghulf, and a unit of 9 flyers, another of 6 horrors, and two of 10 ghouls in blisterskin.
Secondly, gristelgore lists, my best list is Archregent, terror with gk, 3 terror in royal menagerie battalion, 10 dire wolfs and a corpse cart (+cp and chalice)
Third, the classic deadwatch list,blisterskin 1 terror, archregent, 9-3-3 flyers crypt infernal and fill how you please, i've been trying 6-3-3 with 2 terrors, probably the best list still bill souza list (LVO)
and fourth, and in my opinion the best way to play FEC is the ghoul patrol list, i play as blisterskin too, archregent, 2 gk on terror,ghoul ghast 40-10-10 ghouls, chalice cp, we have a nice item against shoting, a good way to engage as early as possible, 4 drops, two terrors... i don't know, if anyone has found another way to play them in the current meta, please tell me. There are som ways with crypt horrors, but i don't really like how they work i feel like we don't have a way to protect our heros to abuse our muster hability against shoting or magic, so we need speed.
