Yeah
fw stuff is obviously written by somebody else that likes 3d3/6 while
gw generally refuses to go over 1d6.
Ghostkeel have an identity crisis but are still OK. Crisis are good when using a homing beacon but good luck getting an opponent to fall for that twice. Riptide are good but expensive to field. Stealth suits are nice, different aesthetic though. Broadside are costly competing with hammerhead and I don't think they come out ahead unless they gain a 2nd support system.
Honestly Longstrike is great, commanders are also. And three units of fire warriors for a battalion +3cp is easy and worthwhile.
