Yeah, 31 is pretty good but the fifths being about 5 cents off kind of throws everything a little out of tune. 5/4 being less than a cent off is great though.

If I had to choose an EDO I think it's hard to go wrong with 41. 3/2, 5/4, 6/5, and 7/4 are all closer to just intonation in 41 EDO than 12 EDO. (I've been casually involved with a local group[1] that's trying to popularize a form of 41-EDO guitar that only has every other fret and uses an odd interval tuning so notes not on one string will be on the next. It works surprisingly well, due to some convenient mathematical coincidences that place all the notes you're likely to commonly use right next to each other.)
