If you are rich, it's the one with potential the highest crit chance. With the white crit gem it gives 25 more crit rating / 0,7% higher chance than f. ex. Erliks Blade of Widows.
[personal opinon] But does that matter with 15 stacks of Reaver, 10 stacks Devastation, and a crit pot? That would take your crit chances to 45% - 50% on Upheaval and CoS. Wreck Armor is already "auto-crit" on opener, while CoS and Upheaval has 30% extra chance of crit on opener. Not sure if you'd be able to tell the difference even if you did 10 million straw man parses. But go ahead if you want the *best offhand*. Personally I feel those crafted weapons never got real bang for the buck. Having an Enchanter buff in group would make a bigger difference. Having a potion of Acute Striking (+135 cdr) active would also matter more than the difference of having Erliks Blade of Widows vs Maniacal Harm in the off hand. [/personal opinon]

If you want to get a T3 crafted weapon for a barb, go for Sogoth instead. Maniacal Harm looks like a dildo and it's not worth all the trouble just for offhand stats.
