As soon as I can, I'll include comparison pages to the documentation, trying to keep it as objective as possible. I can't seriously answer this question in depth here, but it is planned, so at least experts from other systems can also jump in and complement/correct my understanding of each systems. I used a bunch of them, but I'm in no mean expert user of each so making it collaborative sound like a better idea than just giving my point of view.
