Absolutely the best

I’m moving from xenForo to wpForo and am VERY HAPPY with the simplified interface and the pairing with WordPress that allows me to manage the forum better than ever. My forum has over 410,000 posts and 7,300 registered members and wpForo handles it just fine. The wpForo team also logged in to my site to help me with optimization issues. They even made some recommendations regarding hosting specs and theme issues, and continue to support me in the conversion from xenForo.

The paid addons are also excellent and provide awesome improvements to the forum functionality.
