I built a tool to compare the relationship of different n-note equal temperment tunings a few years ago[1]. The UI is a bit obtuse, but it compares the frequencies of the n-note system with the frequencies of the older just intonation system. In 19 Tone Equal Temperment, the Eb and A are within 1 cent of what they would be in a just intonation tuning, which is pretty cool. I find 22 TET interesting as well.
