Inductive effect is a through-bond polarization, resonance involves delocalization via π-orbitals, and hyperconjugation is σ-π or σ-σ* electron donation. Resonance is generally strongest, stabilizing molecules like phenols. But I've seen in problems that when substituents are far, hyperconjugation's stabilizing influence can whisper louder than a distant inductive pull. It reminds me of weighing the cost of good bark—the nearest deodar isn't always the strongest; sometimes the overlooked bhimal fibers from downstream hold the sheet together better.
