I've long preferred New Relic as well - it always seemed the most natural to use; the information that was important was easy to find. Some other APM's didn't even seem to be recording accurate metrics, but ones that did were still more difficult to navigate. I've also had some issues with New Relic - constant problems with metric names exploding. Individual unique urls that saw especially high traffic routinely ended up getting their own unique metric name until new metric name creation would get locked. This would be despite us explicitly naming requests through the sdk. All that said, the biggest reason I still use them is because we're still on some ancient pricing that's a fraction of their current (up until now) pricing. Our rep's been bugging me to get on a call about "renewal" but if our price is going to go up 5-10x I'm moving.
