It’s an interesting question and I don’t have the answer.
My current bike has a 72° seat angle, 68° head angle and 23.4″ ett. It started life with a 70mm stem and spd pedals.
I now ride it with a 55mm stem which can feel a bit short at times but is more fun on the descents. I also now ride flats with my foot in a midfoot position rather than on the ball.
New bike being considered (with no chance of a test ride) is 73.5° seat angle, 66° head angle. I’m between sizes with a choice of 23.4″ 24.4″ top tube. The steeper seat angle is worth about 17mm of reach which about compensates for the stem swap I did way back. Or, I could put a 40mm stem on the larger frame where the who system would only be about 10mm longer.
It’s so hard trying to stay on trend isn’t it.
Don’t forget, the larger size has a taller head tube and both have a lower bottom bracket so the stack difference is greater as well.
