The most valuable aspect for me is having real-time data.
Sigma is accessible for non-technical business users, offering real-time data and easy onboarding, similar to pivot tables, Excel, or Google Sheets. It is valued for collaborative features like commenting, serving as a crucial visualization and reporting tool. However, it needs improved visualization options, a better roadmap for new features, and enhanced handling of complex visualizations. Users also desire versioning features and a more intuitive report creation process independent of data analysts.
