Navicat has an intuitive user interface, powerful backup and recovery capabilities, and excellent performance, but the data modeling tool is too simple and lacks collaboration capabilities. DataGrip has powerful query analysis capabilities, comprehensive database management capabilities, and collaboration support, but it has a complex user interface, low performance, and only supports Windows and MacOS. Therefore, Navicat is suitable for individual users and those who value intuitiveness and performance, while DataGrip is more suitable for those who require collaboration capabilities, powerful query analysis and comprehensive database management.
