Round 1 - Fight.
Which one is better currently?
During Cataclysm, the +22 Int one was better because Intellect gave Spellpower, Crit and Mana.
Now, Intellect only gives Spellpower and Crit.
So I guess the +30 Spellpower is better right now? I've read some comments that also suggested this, but I don't yet have enough reputable evidence for this.
