i don't think most of your points are wrong, but I consider your reasoning flawed - take the competitive example. G/S/C -> R/S/E was the biggest 'jump' in competitive quality, but B/W is still the best, so why would that be used as a point to rank R/S/E ahead of B/W? similarly, abilities are definitely at their best now thanks to the Dream World.
i do like R/S/E's pokemon selection (great top 20), though it's not first for me in that either. and it was the only gen where contests were acceptable and not awful.
