Some consider it efficient for power users. | Modern, context-sensitive ribbon-based interface (like Microsoft Office) that is easier to learn. | | Functionality | Considered by many as the "gold standard" with full feature set and deep legacy support. | Designed initially for numerical calculations, some advanced features from MC15 are still missing or behave differently in Prime 9 and earlier. | | Performance | Generally faster for large worksheets, as it recalculates only the visible part of the screen in real-time. | Can struggle and become very slow with large worksheets (hundreds of pages), recalculating the entire document frequently. | | File Compatibility | Uses .xmcd and .mcd formats. Can be read by Prime. | Can open MC15 files but must convert them to .mcdx format. This conversion is not always perfect and can create problems. |
