All of those products exist because they all have slightly different benefits and drawbacks. What cocktail of analytics products is right for you depends on your specific needs. In general I would say use google analytics (because it's free), and when you want to pull a report that google analytics can't give you, consider what other service(s) could.
Completely agree, which is why I asked the question. I wanted to hear more about the analytics cocktails of others and the startup they are working on to determine which ones may be useful to investigate further if their startup is analogous in someway to the one I'm working at now.
