Visual Studio and Eclipse are typically used for statically typed languages (C# and Java), so you get IDE magic like automatic refactors, renaming, jump to definition, etc. It's nice, and helps you program faster.
However, in the real world most people use dynamic languages like Python, which loses all that IDE magic (AI can kind of help here). btw IntelliJ has been more popular than Eclipse among Java programmers for more than a decade now.
The conclusion is that most programmers don't care about programming more quickly/efficiently.
