William, at the top of this Comparisons and Advocacy forum is a post from Chris K, that has been pinned to the top. If you go down a few responses, you will find some really interesting observations from Chris, about the points you raise. For me, that one discussion is perhaps the best ever in this forum and one of the best in all forums since I started using them more than a decade ago.
