Several people have commented on the ability to move pedal based meters between bikes, yet many don't do that. That is certainly true in my case. Though I did move them some when I had my first and only set. But I have also changed cranks on all of my bikes. If I had crank-based meters, that would have been a big deal. With the pedal based, it's a non-issue.
I'm not arguing that one is better than the other, just pointing out something I did (changing cranks) where the pedal based were an advantage for me.
