Best thing about ResponseTap has to be the direct email and telephone support.

We are a small client and I was surprised at this level of support normally reserved to bigger Enterprise-level clients.
Not being able to listen to calls over 30 days old.
Attribution is the key benefit, being able to understand what works and does not enabling us to optimize performance and not continue with things that do not work.
