Just to add to what MidnightSun said. Battlecompanies especially white scars are doing good. The big one ripping things up right now is a space wolf/ Ravenwing/ Inquistor army list that everyone is trying to play or trying to figure out how to beat.
It has 3 wolf lords, 2 Iron Priest all on thunderwolfs, Raven wing with Belial, librian conclave with Tigirius, Allied Inquisitor, allied Saint Celestine, 2 priest and one squad of sisters, allied Culexius Assassin. Or some version of this I have seen a few different list but many of the same things in it.
General idea is to form one big unit, that consists of: all wolf lords, iron priests, librarian, RCS, inquisitor, priests and saint celestine. This unit (wolfstar) has majority T5, 2+ save with fnp and hit and run with I7. Lots of S9 AP2 attacks (with rad grenades, lowering toughness) that reroll to hit for hatred (priest) with counter attack from wolf lords and auto-passing warhymnes, so unit can reroll failed to wound or reroll failed save throws (2+/2+ or 3++/3++). In general everything that is assaulted by wolfstar unit is dead. wolfstar with dark shroud, so RCS can jink with 2+/2+ cover save, librarius conclave with tigirius rolling for invisibility and belial, whose trait allow extra movement, so footslogging ICs can keep up cavalry and bikes.
I have not faced this or ran it because like the OP I am a fluffy list person that plays mainly orks but I am putting together a Nids list just for giggles since everyone already knows how to take out flying hive tyrants.

God, gives children to people so that death won't seem so disappointing.
