Between the three weapons, and in the context of a Pure level 20 Paladin with KotC Capstone, what are YOUR thoughts on the best THF weapon available now with Sentience available and other RL gear?

After failing to get the ESOS Shard yet again after what must be my 150th+ run of EE VON5/6 over all the lives of my dedicated Paladin character, I'm almost ready to give up on this iconic weapon, despite its undeniable power in the hands of a crit-specialised Paladin with Exalted Smites and all the other damage mod gubbins that make it so gravy.

So, penny for your thoughts...
