I am a Delphi addict also. That is why PPL is so close to it. The PIDE is entirely developed with Delphi.
At my work, I use Delphi 100% of the time. Over the years, I have developed a huge EDI software for our company and without Delphi it would have been a much harder project to maintain and support.
After using eVc and Visual C++ for PPL, I think they are great tools but in terms of visual development and simplicity they are not even close to Delphi. We can't talk about speed since Delphi is very fast.
