git-annex is designed for managing large files in a distributed manner, offering robust version control and integration with Git, but it can be challenging for non-technical users. Seafile, on the other hand, provides a user-friendly interface with strong collaboration tools and cloud integration, making it ideal for teams but potentially raising privacy concerns.
