hey guys, have any of you used Wise Guy Reports(http://wiseguyreports.com)? if so, what was your experience? is the data accurate? they happened to have a report I was looking for but I didn't find much reviews about their services/products online so I'm asking here.

tools targeting desktop software development, like visual studio, Qt, xamarin, xcode, rad studio etc?

Does anyone know up-to-date numbers? I can only find this for 2012-2016. https://www.gartner.com/en/documents/2098416
