I'm not really qualified to judge, since I don't know much about any forum software. Having said that, have you looked at this Wikipedia page?
Discourse stands out as not being PHP (or Java). I personally think that may be a good thing, but I could be wrong, and a lot of people could have strong opinions about that both ways. It seems to be "more modern". The Wikipedia page says it supports threading, but I'm not sure what 'native "real name" support' is, so I'm not sure about that.
