As your reading a lot depends on what type of riding you do, how many bikes you have etc. I only ride a single road bike and when I am riding I am riding, I never walk anywhere except to the bathroom on occasion. So for me SPD-SL were the best choice, easy to get in/out of the cleats last a long time and you can buy them reasonably cheap. As for falling, I did this once the first week I had them and never since, getting out is easy, getting clipped back in sometimes causes me more problems really (but only occasionaly).
