I've still mostly been running cows on my sc javazon in my limited playtime, forever in search of the perfect enigma base ( I cannot ever possibly decide on the perfect base there are too many factors including aesthetics for multiple characters including normal armors such as gothic plate/ancient armor for style points, and even exceptional armors such as cuirass/sharktooth, light/medium armor base based upon that fact, defense, repair costs based on superior/non or usage of ral runes for repairing which I need for crafting caster amulets, so after extreme deliberation I've mostly decided upon a regular elite light(non superior) armor with wire fleece(mostly for my zon's aesthetics) and Archon Plate being the top choices (it's obviously the best in term's of str req/light/defense) and nonetheless dusk/wyrm/scarab/great hauberk are still contender's. Here is the top contender thus far, this was a cracked or damaged archon plate from hell cows I forget which, I cubed it to normal then cubed three sockets out of it and it is 6 defense off of perfect, I still wanted to find a close to perfect defense 3 socket non superior wire fleece, but I'm feeling pretty set on this one...
THIS IS NOT FOR THIS WT I'M JUST SHARING IF THAT'S OK
here's the armor found on my zon rocking eth upgraded titan's, Arkaine's Valor(+2 found off of meph haha), Griffeys, and some amazing rare java gloves.

THIS IS ALSO NOT FOR THIS WT BUT IT IS THE ARMOR I FOUND IN THE PITS P7 ON MY SC BARB IMMEDIATELY BEFORE I FOUND MY FIRST AND ONLY JAH RUNE EVER

So it is a contender except it will absolutely require the usage of ral runes which I want for crafting and if it were to be superior then it should definitely have higher maximum durability (like an archon plate)
A 3 socket superior archon plate is still an option, I just have not found that yet
I have however found the best sp fortitude base ever (it came four sockets)?
