If you're a solo user on Windows seeking a modern file management experience, choose Files. Its sleek WinUI 3 interface with features like tabs and dual panes enhances usability beyond the standard File Explorer. However, be aware that it is Windows-only and might have minor issues in preview builds, making it less suitable if you require cross-platform compatibility or advanced scripting.
On the other hand, if you're tech-savvy and looking to manage your photo and video collections with complete privacy, go for immich. This self-hosted solution gives you total control over your media, but setting it up requires some technical know-how. Avoid this option if you prefer the convenience of cloud solutions or need extensive third-party integrations, as immich has limited support in those areas.
