There is no one GUI standard. Every platform (Windows, Mac, Linux, etc) is different, and GUI is not even standard within a platform. The GUI of current Microsoft Word, for example, is wildly different from earlier versions (and not for the better in my opinion).
When apps like Cyberduck are written for more than one platform, they will normally use cross-platform software libraries (e.g., Qt, GTK, WxWidgets) that often differ from common libraries (and between each other) in order to optimize performance and produce consistent app behavior across platforms.
It just comes down to personal taste. If you don't like the GUI or behavior of Cyberduck, then use something else, because "it's not a bug, it's a feature." Since you prefer Filezilla, that's what you should use. I personally prefer the Cyberduck GUI. I find the FileZilla GUI dated and clunky. "Different strokes for different folks."
