The most useful feature is that it has so many data sources, which makes our job easier in terms of finding insights for various business use cases such as Sales/Marketing or Customer Support team to make better decisions about their products / services usage patterns etc., This tool also enables us automate repetitive tasks using scripts (using Python). Some features like "Custom Reports" are not well developed yet compared other tools out there but I am sure they will improve over time given enough resources from them side! We can easily create reports quickly without writing any code by just dragging & dropping charts we want onto report canvas then adding filters if needed - no coding required at all!!
