I really wish there were more Delphi/VB/WinForms-like visual RAD tools for Linux (Lazarus is just a way too primitive, I've tried it and it feels like neither the editor nor the language has undergone any improvement since 90es).
And I love Lazarus/FreePascal for those very reasons. A simple and very performant tool set that I use quite extensively for a set of mission critical quantitative financial analysis applications.
