I think your poll is missing a response, along the lines of "normal 5 degrees or so, easily held" which would be, I believe, a common response.
On our boat (frac, big main small jib) the amount of weather helm varies greatly with point of sail. Close to beam reaching in a breeze can load up pretty good whereas on the wind it's just about right.
I do think it's preferable to lee helm...
