Which one is better depends on the average damage dealt with each armor-using hit. The larger the size of each hit, the better Platemail is. The break points where Platemail becomes better are at 35 damage elemental hits, 41 damage physical hits, 45 damage elemental hits when using a shield, and 54 damage physical hits while using a shield.

The more armor bonuses you stack, the better Knight's becomes.

In general Knights would perform better than Platemail against physical attackers, but worse against spellcasters. Again, assuming that the Knight's / Ascalon bonus was actually location specific.

Of course all of this is moot as long as Gladiator's Armor exists, as that set just steamrolls all of the other options. You could take off the +20 defense vs. Physical, and it'd still be the PvP armor of choice.
