XF 1.5 Single sign on Xenforo to WordPress


I currently run vbulletin 4.x forums with WP as home page and have vBSSO for single sign on.
Am planning to switch to Xenforo and have couple of questions:

- is it easy and simple to integrate XF and WP through add-on
- I looked up some add-on in the resources but any recommendation that is up to date and has good support?

Let me know if you had first hand experience in moving from vb4.x + WP to XF + WP
