Basically between steel, ceramic, and the UHMWPE lightweight plates available, what's your favorite? I have all three and while the steel is the heaviest, I feel very confident that it will never fail me, but there is the spalling issue and thus I do not like them as a front plate unless I have nothing else, but as a rear plate steel armor is my go to given its durability and slim thickness.
For the front plate, I know it's not Lvl IV rated, but the UHMWPE stuff is so light and has had many videos demonstrating it can stop a dozen rounds before failing that I chose it over ceramic.
