It's better than phpbb for sure. Much easier to manage updates since it uses docker.

It's honestly pretty hard to set up though, they don't have great docs on it imo, but once it's running it seems pretty good.

I like how customizable it is - you can change a lot of functions, and while I haven't done much modding yet, it is nice that it has proper modding support- i added a dice roller and was able to modify it pretty easily.

I think my main complaint is that there's some assumptions about use - for instance, you can only have a single draft at a time (there's a workaround- dm yourself your drafts) and there isn't great multi-account support, which makes it hard if you're doing character-based writing or just want to have different posting profiles - ive been trying for a while to find something like pluralkit for it but it just doesn't exist i think.

Overall, pretty decent. I thought to myself, I could actually see myself replacing discord with this, outside of voice chat
