In which ways is Duality better than Activity?

Your dual would be using more of your 4th function than your activator. So you would get more polr hits from your dual than your activator, in my experience anyway. Your activator at least keeps an eye on your 3rd function unlike your dual which ignores that function and I would think we are more concerned with our 3rd than our 4th. I would get way more Fi assurance from an IEI than an EIE.

Nah, I don't think so, Activity partners see weakness in others that they can improve on, always giving each other advice and at the same time hurting each others weak point. In healthy duality relationship, these criticism is made very lightly, in a way more accepting than if activity ever give advice on each others weak point.

The other problem with these relations is that information between Activity partners always needs some adjustments. One partner may think of it as too foggy and not concrete enough, whereas for the other partner it is too unrefined. Collaboration is also difficult, because partners cannot predict each others behaviour and actions in what seem to be ordinary situations. Because of this, partners cannot rely or count on each other in full. Most of the problems that arise during Activity relationships are because one partner is always Perceiving and the other is always Judging, meaning that they live in different life rhythms.

Although overall interaction between partners is nice and easy, when it comes to fulfilling everyday duties and matters together, partners usually meet with many problems. Instead of solving the problems, Activity partners tend to give advice to each other on how to solve these problems, often affecting each others weak points. The advice of an Activity partner is always useful as it can strengthen your weakness, but not so much that it will ever become your strength.
