The only metric that matters for most typists is familiarity. That's why Qwerty has dominated for over 150 years.

But I'm pretty sure my typing needs as a programmer in 2023 are different from the typing needs of a telegraph transcriber in 1879.

I've been a Dvorak typist for 15 years. I can tell you, without reservation, that Dvorak is a better fit for my work. Dvorak is smooth and comfortable. I can stay in the zone for longer stretches of time.

Nonetheless, Qwerty's killer feature is that it's familiar. Historically familiar. That's enough to keep Qwerty on top.
