Much of what the pecs move in BB style, the anterior delts do in PL style. I'd still say pecs are a prime mover but they share the responcibility. Since the PL style involves more muscle groups, I'd say its more applicable to everyday situations, although I rarely do many pushing movements. Lats, Delts, Tris, Pecs, maybe traps a touch?
If you were a boxer, I'd say both were applicable to "daily life" depending on the elbow position on most of your punches. If you're an offensive linemen I'd say PL style is better for your daily life.
