Turbo Pascal was completely amazing. I remember resisting it for a long time, because IIRC it implemented non-standard Pascal. But the competitive tools were less powerful and far more expensive, (e.g. the Microsoft tools). And then I tried it, and was completely blown away. I no longer cared about the non-standard stuff. I had a fast intuitive IDE running on my original IBM PC.

As for modern IDEs, Intellij has been orders of magnitude better than any competition for more than 25 years (I think). I have stayed away from Microsoft products for a very long time, so I can't comment on VSCode and its predecessors. The main competition I remember was Eclipse, which I always found to be sluggish, unintuitive, and buggy. The fact that it wasn't even mentioned in this article is telling.

JetBrains, the company that created Intellij (and then PyCharm, CLion and many others) is one of those extremely rare companies that defined a mission, has stuck to it, and excelled at it for many years, and has not strayed from the path, or compromised, or sold out. It is so impressive to me that they maintain this high level of excellence as they support a vast and ever-growing collection of languages, coding standards and styles, and tools.
