PX has robust functionality that enables lead buyers to assign appropriate payouts to each respective publisher based on historical performance. They have a nice suite of integrations with third party lead validation and compliance solutions. Their product team lives and breathes host and post lead generation, which gives them a great pulse on upcoming trends. Review collected by and hosted on G2.com.

I'd love to see more options under the campaign settings section, such as geo-targeting or day-parting options. Review collected by and hosted on G2.com.
