I can recommend you what I use, I don’t think they’re too far from the meta though.
The question is, will the crafting system allow you to replicate what anyone recommends? 
My main builds per class:
Ogyrn
Curios are whatever, just did a lot of health.
Psyker:
One toughness two health
Veteran (I haven’t done enough testing post the changes)
two toughness and one health curio.
Zealot:
1 toughness 2 health curios
