Cyberduck

Pros: Cyberduck has become my go-to app for transferring large files. I use it to archive large media files in the cloud. The interface is clear and it has been easy to connect with secure, cloud-based storage services. Uploading and downloading is easy. The developers update the app frequently. Best of all, it's very inexpensive for a reliable and well-supported piece of software.

Cons: The interface is plain - fine when compared to most FTP programs, but novice users might be more comfortable with a more graphical UI. Also, like other FTP programs, uploads or downloads pop up a small status window that could get lost behind other windows easily. It would be nice to have it all in one interface. Finally, moving around in my online storage spaces is slow, typically taking 3-5 seconds when going from directory to directory. Overall, these are minor inconveniences.

Overall: Cyberduck is simple and secure. It does what it does well, but doesn't do anything else. It's compatible with every major cloud vendor and all FTP standards. There's really no reason to use anything else.

Pros: Easy to use interface with a drag & drop view
Open Source & Free to use
Integrate with most of the major cloud storage providers
Built-in text editor
Excellent bookmarking feature
Available on Windows and Mac

Cons: Not available for Linux , apart from that it works great.

Overall: Cyberduck is one of the best FTP solutions you can get. It has a great intuitive design, supports advanced SSH access and is free to use under GPL license. It even provides integrations with many advanced text editors making it even more recommended as an FTP client.
