Power My Analytics and Supermetrics provide relatively similar features. Both tools offer data source connectors to the most popular marketing platforms, don't have any data transformation and normalization features, and don't provide data storage options. Between the two, Supermetrics offers a bigger number of connectors and, most importantly, destinations, while Power My Analytics connects only with Looker Studio, Google Big Query, Google Sheets, and Microsoft Excel. Companies with advanced marketing analytics needs and larger data usage tend to choose other Supermetrics alternatives, like Improvado or Adverity.
