I generally like SFJs. I generally dislike STJs. That said, there are notable exceptions. A few SFJs are on my permanent shit list, and I have a few STJs I wouldn't trade for their weight in gold.
I get along well with most SFJs because we share Fe/Ti. However, the Si inability to see outside the box is often an issue until they can develop some Ne. Otherwise, they're unable to keep up with or respect my perspective, and when people get bent out of shape with me for being myself, they end up fired from my life in a hurry.
There are very few STJs I've been able to have long term relationships with, as they almost always manage to misinterpret something I say or do, then get pissy about it, and all of a sudden the tolerance between us is gone. Granted, I have had to learn that they aren't inherently ill intended stuffy self absorbed pricks... and that has helped me tolerate them. But, if an STJ has a well developed Ne and Fi, we often are able to get along very well, especially if we limit our contact to small doses.
