I think there is an inherent demand to put everything in numbers. Which camera is better? For most people this is the same question as "Which one has more megapixels?".

A summary like this one is very helpful for new users, but it should not give a false sense of security, which too much "numbers" and "ratings" may do.

It's ok to list things like "uses own chips" etc, but after all it boils down to one question: "Safe to buy from this vendor?". Which would be "Yes" for companies that deliver on time (even when they offer preorders) or "No" for companies which do not deliver on time, do not honor refund requests etc...

Of course you put much work in this, but maybe you consider this for the next version of your guide.
