Talend is significantly easier to use.
Talend Open Studio offers robust data integration and preparation, connecting multiple data sources and creating a golden record. It excels with NoSQL database integration and supports data transformation and custom component creation via its SDK. Quick, professional technical support benefits users, though Open Studio's excessive resource consumption and limited error handling hinder performance. Installation issues, inter-version compatibility, and limited features in the open version require attention, with documentation needing significant improvement.
