+1688 Stamina
+1211 intellect (OH Int enchant included)
+7478 Spell Power
+405 Haste
+360 Mastery
+331 Spirit
+287 Crit
+1 Blue socket with 60 Crit bonus
Total Spell Power (w/o accounting for the socket) = 8689
Total Secondary Stats (w/o accounting for socket) = 1383
Assuming normal Sha-touched staff:
+1835 Stamina
+1223 Intellect
+755 Critical Strike
+852 Haste
+7006 Spell Power
+1 Sha-touched socket for another 500 Intellect
+1 Prismatic Socket (Eye of the Black Prince)
Total Spell Power w/o Prismatic Socket = 8229 (8729 with Sha gem)
Total Secondary Stats w/o Prismatic Socket = 1607
Edit: Forgot to account for the Prismatic Socket from the 5.1 part of the Legendary chain. If you are willing to use it on the Sha-Touched weapon then it is your best bet in terms in all regards. If you don't have it then the MH+OH is slightly better if you use a Purified Imperial Amethyst (slightly more spell power, slightly less secondary stats) but the difference is so small I wouldn't sweat it.
