If you're a Mac user seeking a simple, keyboard-driven tool for managing your window layouts, Rectangle is your best bet. It’s free and lightweight, offering sensible default shortcuts that enhance your workflow without unnecessary complexity. However, if you find yourself needing advanced layouts, be prepared for the added cost of a Pro version. This tool is not suitable if you're not using a Mac or desire a comprehensive suite of features beyond just window management.
On the other hand, if you're using Windows and want a modern, feature-rich file manager, choose Files. Its sleek WinUI 3 interface with tabs and dual panes improves productivity over the traditional File Explorer, and its open-source nature means it’s continually being improved. However, it may not align with your needs if you require cross-platform support or advanced functionalities like FTP or scripting capabilities. In summary, select Rectangle for efficient window management on Mac, and go for Files to modernize your file handling experience on Windows.
