Unfortunately no, had no use case for it in an industry dominated by Python and C++. Wouldn't be surprised if Lazarus is very fast and pleasant to use, and I think the problem with more popular IDEs lies in underlying technology: C++ is traditionally very slow to compile and analyze, and many popular languages are too dynamic for reliable autocompletion to be feasible. When I briefly worked with C# and Java in 2000s the IDEs were very much fully functional (compared to C++ at the time), but sluggish enough to be unpleasant without a powerful PC which I did not have — and Delphi ran fast on cheap hardware.
