Moving to the corner requires a swipe, pickup, and swipe. Moving the mouse to the bottom can be done in a single swipe.
I've got an ultrawide and it doesn't require that at all; moving the start menu to the center to compensate for bad mouse speed settings is like reducing display resolution to compensate for bad text/icon size settings.
My eyes aren't good enough for that all the time, and sometimes, the cursor is hidden, so it doesn't even matter.
Getting to a corner has a predictable way to get there
