Xenforo is by far the standard bearer for adaptable forum solutions. But everyone and their uncle is running xenforo now, so I thought Id give phpbb a try as it's less server load and loads faster. Better for SEO. We are at a A rating from GT Metrix right now so that's perfect
I am very much a Xenforo fan and have been since it was released in 2010! I remember before Xenforo I was using vBulletin but when they upgraded from 3.X and onto vBulletin 4, I didn't like the upgrade and was happy to see a new option which was Xenforo.
