But btt it's just a simple matter of stat weights, simcraft is your friend here:
Assuming 465 pieces you look at:
(459+147+189)*haste weight + 114 * mastery weight + 426 * crit weight
vs.
(459+459)*haste weight + 228 * mastery weight
Or in other words: With the complete set you just lose 123 haste and gain 312 in crit/mastery. Does 1 point haste really sim 2.5 times better than either crit or mastery? That's highly unlikely.
