It indeed depends on the wearer's skills and specific needs— a front-line fighter is likely to wear heavy armor, but not always. A monk, for instance, would find that to be a hindrance, and tends to go without any armor at all. Someone like Astarion prefers something light, a bit of leather and nothing more, just enough to keep a dagger or stray arrow at bay. For me, anything heavier would be a hindrance when casting spells, inhibiting movement and causing distraction.
