I love this tool for a number of reasons. The reporting section is wild - the degree of analysis you can do is unmatched.

I also like that it's not integrated with GA and doesn't rely on UTMs (which are now less effective thanks to Apple). I can create more than just metrics, but view customer journeys, make comparisons and more.

I think the key to KM's magic is access someone from support to work through it with you. I highly recommend.
