Swift Girding, lets you don a suit of armor as a Standard Action. You can't sleep in Medium or heavy armor, and few things are scarier than the evil gleam in the GM's eye when he asks, "Are you sleeping in your Armor?
Yes, and you wake up Fatigued. No, and you will be fighting wandering monsters in your underwear. With Swift Girding, you can dress as a Standeard Action and move in in 1 Round. Normally, it takes minutes for you and assistant to get into your armor.
Divine Favor, mechanically, is just straight up great. You will have a +3 to hit at lvl 9 (maximum).
True Strike, however, lasts all campaign. +20 to hit, whenever the absolute &%$* you want.
I still say True Strike, personally. 2/day, you can almost literally succeed at striking, especially when you need to regardless of the BBEG's AC.
