Or none of the above, because they are all completely irrelevant / useless ?

I've watched the side stick vs. yoke debate go round and round on these threads, and come to the conclusion that either I don't understand the controls / laws, or the whole debate is completely missing the point. I can't see that it matters on a bus what size the stick/yoke/whatever is or where it is - and that is not because I think there cannot be a feedback problem, but because I think if there is one, it is elsewhere.

However, I don't think anyone one else has made the point / connection, so maybe I am completely confused.

Perhaps someone who acutally flies the thing can answer the following to clarify:
Assuming a 'bus in normal law, as PNF you scan the current position of PF's controls - be it the sidestick, a hypothetical yoke, or a dot on the pfd, or whatever. You see PF, right now, has "stick" in neutral. What does this tell you about what PF is commanding the a/c to do ? [say pitch axis, is the command to climb, level, descend... that's what you want to know, right ? ]
