Maybe it's a sign of age, but my daily driver is an Apple Extended keyboard from the G4 era (around 2002), and the angle, layout and throw is unparalleled with anything newer from Apple. This is the black-on-clear variant, with full-height top row and clear plastic margin surrounding the keys. Their current offerings in the desktop keyboard field are particularly uninspiring.
They made a LOT of the G4-style keyboards, so finding them new in box or minimally used is not all that difficult, and if I was to start a new project with unlimited budget, I'd go with a new-in-box one.
When recently forced to use a run-of-the-mill Microsoft keyboard, the only major adjustment during coding was the backwards Cmd and Option keys (Windows and Alt).
