If you’re a solo user on Windows looking for a modern file manager that enhances your file navigation experience, choose Files. Its sleek WinUI 3 interface, dual panes, and advanced tagging features make it a superior alternative to the default File Explorer. However, avoid it if you need a cross-platform solution or advanced features like scripting and FTP access.
On the other hand, if you’re a Mac user who prefers a keyboard-driven workflow, Rectangle is the best pick. Its straightforward window snapping functionality is efficient and user-friendly, especially with its sensible shortcuts. However, consider looking elsewhere if you're not on a Mac or if you require an all-in-one utility suite, as Rectangle focuses solely on window management and advanced layouts require a paid upgrade.
