Is there any Cloud Storage GUI for Mac? On my iPad, I have GoodReader, as well as ReaddleDocs, and both allow me to connect to a large assortment of Cloud Storage providers. On my Windows machine, there are the Cloudberry Lab assortment of products. On my Mac, there are less options.

I have a license for Syncovery, and have been using it since it was called "Super Flexible File Syncronizer". It works great for large pushs and pulls, but doesn't have a great GUI. It also doesn't support as large of an assortment a I would like.

I found Interarchy 10 and DragonDisk. However, the best front-runner right now is CyberDuck, though the GUI is not super shinny.

Am I missing any options? Paid or free is fine, as I don't mind supporting any developers for work they do. If it can have the Mac skin to it, it would be awesome!
I haven't tried it yet, but the folks behind CyberDuck have released Mountain Duck, it allows you to view remote resources as volumes on the desktop (i.e. integrates Azure, SFTP, S3, etc. with the Finder).
