It depends entirely on your level. Since you seem new, you'd best be off playing a few points into Body Armour Expert, which works better for low levels. However, eventually, your armour gets so turtley you can no longer bother improving it, so by the time you get 500+ physical protection, put as many points as desired into Tough Body.
