Eh, I personally prefer the Blessed Shield. Aside from the healing it provides, which works perfectly with Saints, halving damage taken from Terrors is quite useful, and usually worth more than the 7 Def, while also not weighing one down. It makes your Saints actually able to combat Gargoyles and Bigles, especially Cleric Faye. Of course, it doesn't work on human enemies. However, you already have Steel Shields, and can gain access to a Dracoshield very soon, which really speak against the Silver Shield's usefulness at that point.
