I'm not certain if the case is the same in the U.S., but I think it would not be a hasty generalization to state that RBC's "Our Daily Bread" is the staple pietist "devotional" literature here in the Philippines. I used to be one of the consumers (stacks of the booklet still bedeck a part of our storeroom). Needless to say, I wouldn't recommend it to anyone desiring their daily dose of spiritual high. In fact, I wouldn't recommend seeking such highs.
Lest I be taken wrongly, I am not advocating the notion of the unimportance of private devotion. Private Bible study and prayer are indeed important—but they take a back seat to the corporate expression of piety that is manifested in the context of the visible church (read: attending the Sabbath meeting, expecting the covenant of grace renewed through preaching and ratified through the Sacraments). Approaching private devotion in the attitude of seeking emotionally-charged theophanies is a recipe for grounding one's sense of assurance on oneself (subjectively) rather than on Christ's person and finished work (objective), and that would be precarious.
But if you must insist, I can recommend D.A. Carson's "For the Love of God" for your daily devotional needs (just beware of Baptistic innuendos every now and then)—AND THIS(!):
