Weighted vest vs. ruck plate carrier — which is better for rucking?

r/Goruck and r/Rucking threads consistently split on this. Plate carriers concentrate weight high on the back (closer to a loaded rucksack), which most longtime ruckers prefer for distance walks. Weighted vests distribute load front-and-back, which many reviewers find more comfortable for HIIT, calisthenics, and shorter walks but less ruck-like for serious training.
