What year is this? These discussions were worn out long ago.
In the early years, some DAWs used to sound slightly different. Due to either implementation of proprietary hardware (Pyramix, Paris, Fairlight) or poor coding or hardware design practices (mostly early Pro Tools). For instance, Pro Tools "Mix24 " was broken from the beginning with 56 bit internal processing linked in hardware by 24 bit interconnect stages that could cascade to exceed 0dBFS when levels should have remained below clipping in theory. There are other examples of variations in DAW results for various reasons. Google the “Awesome DAWsum” test just for fun.
Those days have passed. There may be some DAW or other that has flaws in it but as a rule, they all sound the same. The ease and intelligence of the workflow design has more to do with results now than any other factor. And one size does not fit all there.
Our great American poet, Michael McDonald said it best long ago: What a fool believes, he sees, no wise man has the power to reason away…
I like Nuendo. Because of the workflow.
