What active iconic PL stance do you prefer for Paladins? My thoughts:
Aasimar scourge - 3% double strike. Decent but probably won't notice it.
Bladeforged - 30 Repair spell power. Useless unless you're Bladeforged.
Deep Gnome - +3 illusion DCs and 15 Acid spell power. For GCS builds.
PDK Knight - Rally boost. Big negative is duration is small compared to the permanent buffs other stances provide.
Shifter - +3 damage with melee weapons. Good, maybe best in my opinion. Paired with monk that's +6 damage which is noticeable. Downside is you have to do shifter lives.
Shadar-kai - some weird displacement proc. I don't know, I've never understood this PL stance. Seems highly situational.
Sun Elf - 30 light, 30 good spell power. Useless.
Tiefling scoundrel - 30% striding. Removes the need to use expeditious retreat clickies so more of a quality of life thing.
My top 3 would be:
1. Shifter - seems the best most consistent advantage
2. Aasimar scourge - at least you are getting double strike but I'd put shifter clearly ahead here
3. ? PDK for the party boost?
