judging functions you share the same rationale, perceiving functions you see the same things.
same functions in a drastically different balance can be stressful, like the other is misusing the functions or seems "shallow" or "overly ____."
functions of opposite orientation, when healthy, can be really great. a lot of the greatest relationship matches seem like the same function in the opposite direction. it gives like a completeness to the function, Ne-Ni, Fe-Fi, etc. i seem to know a few entj-intp couples too. i've seen a lot of estp-istj evidence as well.
i see a lot of relationships possible. entp-infp conflict is how i relate, as infj, to entj. my first judging function (aux Fe conflicting with dominant Te). or how much i like people with strong Ti, bc that's what i feel ooh'd and ahh'd by right now, what i need to develop.
