The OP says accuracy and reliability are MOST IMPORTANT.
With the guns he listed, he will not notice a difference in these areas. One or the other might be marginally better in each of these areas. P226/9's aren't more reliable and accurate to the point that even an expert shooter probably won't be able to tell the difference, especially at combat ranges (as far as accuracy). If they were, they would have a much bigger market share than they do.
Not saying they're bad guns, they certainly aren't, but any of the guns he has listed are very reliable and very accurate.
