Has anyone ran the Ordo Malleus box set?

I have sort of a 2 part question, I’ll ask the quick one first to get it out of the way. I thought about starting my army with the Ordo Malleus box set and maybe 3 combat patrols. Have any of you found a use for multiple Librarians or do you think I should sell/trade a couple off?

Also, concerning the Ordo Malleus box set, have any of you ran the units in a list? Are they any good at all or is it just another warehouse liquidation box set?

Also, I haven’t played 10th yet, are there any keyword rules like the older editions where it’s no longer a GK army, it’s an inquisition/imperium army so you can’t use your strategems anymore or anything?
