It’s not really fair to compare something that was cutting edge in 2004 to software that didn’t even exist until 2013.
vBulletin5 isn’t half bad in terms of features (it’s a lot more reasonable to compare with Discourse than vBulletin3 at least) but we never got to see it in action here.
I’ve used a lot of different forum software over the years (as both an admin and as a user) and I like Invision Community the most personally. It’s not perfect, but it’s pretty easy to adjust to your preferences. The Evernote Forums use it if you want to see a live example. Edit: Or you know: the actual official forums for Invision, not sure why I forgot about that.
