Between a D shaped and a circle shaped binder ring which is better?

Answer 1

I have a large binder with a D ring and I find it annoying because the pages have to deal with the shape of the ring - and sometimes it becomes difficult to turn the pages over the bend of the ring - probably hardest with the very large binders.

Whereas with a circle ring, it doesn't matter which way the pages lay - you can easily move them back and forth . Unless - they don't close completely, and then they become super annoying to turn the pages - as the pages slip into the separation and 'catch'.

But if I had to make a choice, I'd probably go with the D Ring.
