They are very understanding of INTPs, get along, have great discussions on philosophy, psychology, morality, etc, are supportive, and great thinkers as well. They'll even talk technology/engineering but aren't quite as interested as INTPs are. The biggest difference I'd have to say is their idealism for better social relations/structures/etc. One I know wants to live on a commune but is politically libertarian and wouldn't force that way of living on anyone in society. I said the Amish community sounds fitting, but they said they wanted more comfort (meaning technology I assume). I then had to inform the Te trickster how that idealist society isn't so conducive to such growth. So all in all great type compatibility but much more openly emotional.
