The last time I used a HKSK storyteller was in alpha 13 with Hildegarde on 2nd or 3rd highest difficulty (They changed names), and my god I never got a break, it was raid after raid, my colony wealth just kept going up because of all the loot on the map, and I was just quite literally overwhelmed not because it was impossible, it was tedious as fuck checking items/ammo/clothing etc.
Edit - Since then I've always stuck to the vanilla storytellers, perhaps I should give them another go.
