I could see aeb-l, and 13c26 being more dependant on that. Since theyre ingot steels. I imagine the processing could have a big impact.
Also, idk how strict they are with 13c26 on their sulfur and phosphorus levels. If the tolerances arent as high that could effect it.
But anyway. I think for pm steels it doesnt make a huge difference, from what I've seen. Like m390, 20cv, 204p. They are basically identical.
The real thing that is going to matter, is the heat treatment as far as how one performs vs the other (disregarding geometry of course). Also who knows. Maybe one heat to the next the difference seen due to different levels of the alloying elements, you could even see a bigger difference between the same steel, than from one vs the other.
