I'm Glad Someone Remembers C++ Builder
I did a bunch of (IMHO) really good work in Delphi when it first came out, replacing previous apps written in VB. It was a revelation at the time, dropping that awful BASIC dialect, but my heart definitely belonged to C++ at the time.
When C++ Builder came around I jumped across quickly, and it was my go-to tool for many years until I moved entirely to Linux at home and lost the ability to choose my own dev tools at work.
