In this survey IDE users rated several features/functions of their favorite IDE.
So the report shows the satisfaction rate of users about their IDE.
From the eight rated EDIs, Delphi holds the sixth place.
Features where Delphi has relative high score are the compiler performance, ease of use, performance resulting applications, debugger, editor and integrated third party tools.
The Delphi compiler performance has the highest rate in the survey.
Among the lowest rated features is the documentation, which will be no suprise.
