Best possible Minecraft PVP gear?

So right now I'm on a multiplayer server and me and a friend have battles here and there to see who's strongest I've been using a Sword -Sharpness V fire aspect II knockback II, Bow-Flame power and punch all maxed along with full protection IV armor with thorns on the chest and depth strider and feather falling on shoes. I also have 10 god apples and 10 golden apples if I run out of the others, also strength, regen and swiftness potion, with enderpearls in my hot bar, he has basically all the same but 4 totems of undying so am I screwed or is there anything else I can use to my advantage?
