On the other hand, I have witnessed LSI-SEI Benefit relationships that ended in tears - and the aggressor-caregiver thing wouldn't have helped.
For rationals, Illusion is better from that PoV than Semi-Duality; for irrationals, it's the other way around.
Generally speaking, I tend to think that Victim-Victim is particularly unfavorable, so Gamma NT and Beta NF mirror and identical relationships will be less promising than Alpha SF and Delta ST mirror and identical - and, indeed, than Beta ST and Gamma SF mirror and identical (I have known a few Alpha SF mirror couples that overall did well).
A couple I know very well is LSI m - ESI f - kindred, and aggressor-aggressor. He seems sometimes a bit depressed due to the lack of Fe but overall they're ok.
I happen to know even a quasi-identity couple - SEI f, ESI m. That's not really favorable but in their case it seems to work due to their being both in their second marriages, and already rather old - so they just accept each other as they are and avoid open sources of disagreements. I talk a lot to the ESI guy, and he essentially accepts her SEI-ness as "just the way she is" - even as he clearly doesn't understand it - but in a good-humored way.
My basic point is that while it doesnt' affect the broad duality-> conflict worsening progression, I think that those factors make the precise ranking more complicated.
