WinForms vs GtkSharp with Mono

Question

When developing with Mono for an app to be run on Windows and Mac OSX (and maybe Linux) which would you suggest, WinForms or GtkSharp for the GUI and why?

Answer 1

When deciding whether or not to use a cross-platform architecture, gague your requirements of having a tight UI against agility toward change and development time. Using a platform-specific UI framework is (almost) always going to give you better looking and better performing results than you'll get from a cross-platform one.
