I cast my vote as ISTP, if I had to pick one.
My mother is an ENFJ and my dad is an ISTP. They fight a lot, and my ISTP father was a bit more balanced when they married (He was 41 and she was 28, so now he's pretty ancient), but it's a good marriage. The problems occur when he gets restless and insensitive or she gets a bit too controlling. But I find they balance each other out nice. In best cases, he's the engine and she's the steering wheel.
Also, I find ENFJ's generally aren't as attracted to INTP's, but then again I only know a few ENFJ's.
Yes. Even though I don't advocate using type to screen romantic interests, people have got to remember that the mythic and fabled INxJ/ENxP relationship (and ESxP/ISxJ) does not create the same type of reactions as ExFJ/IxTP (and ExTJ/IxFP). Dom perceivers getting together don't have each others opposite inferior function to deal with unless it's ENxP and ISxJ and INxJ and ESxP.
Dom Fe and Dom Ti interacting often requires a maturity or rather positive interaction with each others inferior so that it doesn't rattle and jar each other. If I use these forums to judge, I know that I prefer the INTPs that are older typically 30+ and the younger ones I sometimes just want to dash to pieces.
If ENFJs and IxTPs do embark in a relationship together, I think ISTP /ENFJ fares better than INTP/ENFJ. I think this depends actually on the ENFJ's function strength rather than the INTP's. If an ENFJ has a pretty strong Fe-Se loop then I think ISTP will be more appealing because there will be a greater desire for physical action, impact, and movement that the ISTP can provide. ISTPs get The Itch and so does the ENFJ and I feel like an ISTP naturally knows how to fend off an ENFJ if they get out of control better than an INTP. Honestly, INTPs seem to wilt after awhile. If you have an ENFJ with weaker Se and reasonable toleration of Ti then the INTP will look more appealing. Ne often doesn't really need to
do anything and if the INTP has stronger tertiary Si they tend to be more comfortable exploring settled routines and familiar patterns while the ENFJ eventually needs to start roaming.
ExTPs and ENFJs don't seem to interrupt each other as badly either. I have a very strong respect for TJs because I get the structure of extroverted judgment even if it can sometimes seem harsh to me. It's so funny, in my department at work we have one TJ and the lack of Te (tertiary and inferior of FPs and shadow FJ and TP) is very apparent. There is absolutely no structure except for Feeling structure with Fe being more apparent because it's extroverted but Fi being equally manifest even if not as conspicuous. So well have all the FJs and even the TPs feeling something's amiss and reacting to that and the FPs walking around as if nothing is going on but emitting rather strong waves.
I'd also like to add the ASO's observation has worked well for me. Two of my best friends are INTJs and we get along better than what is often reported on the MBTI forums. I do notice they tend to go for FPs and that often ends in blistering infernos but whatever.
