I use a dactyl manuform 4x5 with the miryoku layout. I took some time getting used to the key placement and mod taps but it's impressive how little one moves their hands when typing, even for numbers and symbols. Hasn't changed how fast I type though.
Back in the day, Delphi had the best form designer by far, which to this day is still unsurpassed in some aspects (visual component inheritance anyone?).
The code-oriented portion of the IDE was also decent, IIRC, with very fast edit-compile-debug loop (something Borland was traditionally good at from TurboPascal days), a capable debugger, and excellent hyperlinked and contextual documentation.
But I haven't used it in more than two decades and it makes me sad if it's really true that it's no longer good.
Winforms supports Visual component inheritance, though not as nicely as Delphi used to around V3-5 which I used.
I also loved Delphi's WebBroker technology, their visual web components were awesome and that tech was so far ahead of it's time I still pine for it. Was writing compiled ISAPI web performance, with fast development, huge amount of high quality libraries, and hot reload! In the year 2000! The only tradeoff was manual memory management, and I guess lack of generics and LINQ.
