Magnificent says I!
I like the inclusion of "psuedo-reserve feats" for most (all?) of the domains and schools-- it's nice to provide wizards and clerics constant opportunities to wield arcane and divine power without running completely out of spells-- the inclusion of being able to cast signature spells (i.e. shield or magic missile) with greater frequency as they level is nice as well. I also notice that these reward players who stick with the base classes, whereas prestige classes from 3.5 granted domain/specialty slots for all spell levels, including those earned using boosts from said prestige class.
