Interested to hear, what's personally your favorite/least fav Personal Skills in Fates and why?

I will forever be grateful for Fates introducing personal skills, what a neat way to give everyone at least a little bit of uniqueness, even a little, no matter what. I like a lot of them like Peri's near omni stat raise and Charolette's Unmasked. I remember always thinking like Selena's fierce Rival was really, really situational and how odd Izana's actually inflicted a flat penalty damage to your allies as well
