My company is currently looking for a solid A/B testing framework for our Rails 3 apps. The only one I've had experience with is Vanity, though there seem to be at least 3 other strong contenders. So we would love to get input from the community to help us choose between Vanity, A/Bingo, Mountain Goat, and Split:
* Vanity

* A/Bingo
http://www.bingocardcreator.com/abingo

* Mountain Goat

* Split

Thanks!
