meh. to me the offering of segment carries very little benefit. it's great being able to swap in and out of different SaaS but honestly, I did not find the value offering to be significant because you end up fiddling with less than 3 or 4, 10 at extreme cases.
Ultimately, I ended up going with Mixpanel because they offered pretty much everything I wanted in analytics. I have integrated Segment everywhere but ended up ripping it all out once I realized that I had bought into the marketing.
