The ability to have great integration with Google Analytics, AMPscript in Marketing Cloud or any other 3rd party tool you may need! I cannot think of anything specific at this time but we are using it so much internally now as well as externally across our agency network - its been very useful thus far!! We're able solve some problems/ questions around tracking conversions without having multiple different tools which can be confusing when trying figure out what's going wrong within each individual piece vs another one etc..
