I haven't really seen the PvP-gear so I don't know how it is compared to the loot you get from hardmodes. I just know that the hardmode loot is ilvl 126-128. Also, you do get Columni Unassembled stuff from some of the bosses in hardmodes, which has an even higher ilvl. As of now after running about a week of hardmodes +1 run EV I am almost fully epic with most stuff being Columni.
