The thing about reporting/dashboard tools is the more integrations, options, and features, the more complicated and expensive it is. But, each campaign can have unique characteristics, so customizing one column might be very important for it to show value. That being said, here is a list in order from simplest to most complex and price goes with it from my experience (I left out Google Data Studio since it has been mentioned already):
Cyfe,
Klipfolio,
Tap Clicks,
Datorama
