As far as regular equipment, generally the str increase between ilvls will always be better than the combination of the secondary stats. So once again, unless you really need the accuracy always go with the higher ilvl. Now if you have two items with same ilvl, this is when the secondary stats come into play. Use their values to find the value of your gear and you will know which one is better to start modeling around Eorzea.
