Windows app GUI is a joke. After people widely used Windows for over 20 years, their cluttered interface never got any better having 10 menus, 20 buttons shown at once where many of Mac apps got that right with simpler and effective interface.

If I have the option to choose between WinSCP and Transmit, Transmit is the obvious choice. CyberDuck interface isn't as bad as those Windows only ones but not as polished.
