The ability to have both an end-toend view for ETL/BI as well has multiple views including report generation was great! I wish we could use this tool more often in our organization but it's very good at what they do especially with having so many different tools out there today you can't be too picky about which one fits your needs best if any really fit them all will work just fine!! We were able solve problems related mainly around master sourcing from legacy systems into Salesforce using these connectors along wtih other sources such as Google BigQuery etc..
