I got me the AS plate and the OC plate and while I haven't compared them to the standard plate yet, the OC feels basically the same as the standard plate and the AS plate has more blade feel, but it's more of a "Hello there," rather than: "You'd better be on guard."
On 2-3 days' worth of growth, the results were basically the same.
I guess with the AS plate, the angle is a little easier to keep, due to how the blade lets itself be known, but with any of the three plates, if I feel the blade, I know the angle's off.
