Why vB forum have less resources than other software forums?

vBulletin over the years, have been being the "KING" after Developers go away from vBulletin (this happened a long time ago) they decide to start a new adventure
If because of that Xenforo is now treading like a boss.

vBulletin have serious problems, it is buggy and their Admin Panel is ugly (in my opinion).
Their price are very high for what they offer, if you look at Invision Power Board (IPB) offers better..

Their Install is not easy to setup (is not hard, but if you have newbie you will be furious or disappointed with their installation process) < Keep I mind, I don't know if this have been changed, but the last time I tried to install, it needs to configure manually some files, not funny.

Well Xenforo is treading of course, and is much better than vBulletin (where is the new version of vB? vb6?)

It was great time since vBulletin had sucess, they could be the king again, but they "stop" in time. You know..

Now IPB and Xenforo are the most used in case of paid forums.
