I never used VS/C#, but can you drop a TDBGrid connected to a TDataset and then just resize autoloaded columns to your taste? Discussing tooltips on a listbox in RADs is like discussing colors of pencils in a hi-tech workshop.

>>Web and mobile development (which I have done all 3) are significantly slower

The above will probably take half a day in web development (assuming an experienced developer), so no, they aren't "totally wrong" at all.
