To me, Lazarus is the golden standard of IDEs, because Lazarus is built in Lazarus and the author really knows how to dogfeed his own product. So many examples and tutorials, it's really awesome for teaching kids how to make programs.

I mean, it's really an IDE similar to what we were used to later with Microsoft Visual Studio, when it had integrated tagging, search, help, API docs, widget examples and libraries etc.

Every time someone tries to tell me what an IDE is, I say nope, that's not an IDE because nothing is integrated there. Xcode could be argued is an IDE (still) but it's a painful one in comparison with Lazarus.

But what do I know, I am so stubborn that I build my own UI frontend framework in Go for the last 6 months because I refuse to go back to the JS world. Hopefully at some point I can make an IDE with that, but who knows how much timd I need for that...
