The Cessnas & Piper trainers I have flown seem to be quite tolerant of aileron use right down to power off 1g stalling speeds, I assume at least partly because of the washout in the wings (causing the wing root to reach critical AoA first, leaving the aileron bit unstalled.) Also differential ailerons help... So left aileron will always cause left roll, and right aileron right roll provided power is below cruise settings. At least that is the case in my experience.
The Robin 2160, with no washout or differential aileron gearing, does allow a nice demonstration of aileron stall at high AoA, but even full aileron use in the stall just arrests further roll and enhances buffet. It does not seem to cause adverse roll much, provided of course one is reasonably in balance.
Never tried pro-spin aileron. I think you would just enter a spiral dive with possibility of aileron roll.
Most controllable aircraft I ever flew was the two-wing (fore & aft not one above the other) Eagle 150. Stick fully aft and the aircraft descends nicely, slightly nose-high, with full aileron authority!
