Forsaken sanctums vs normal sanctums

O7 im a relatively new player (4 months old) and ive spent the last 2 months ratting in nullsec when i came across the forsaken angel sanctums. normally i thought its a better/harder version of the normal sanctums but for the love of me after doing over 30 i never got a faction spawn or an escalation and the isk is the same if not worse. am i imagining things or normal sanctums are better? (ship i use is a vargur)

first i am not sure that this question belongs to New citizens Q/A

i don’t know about angel version, but for sure serpentis forsaken sanctum is1) a bit harder than regular sanctum, and is easier to do in a marauder 2) the bounty is significantly higher than a regular sanctum
