On the App Store both sit at effectively the same score — 5.0 for Re against 5.0 for Diagram. That said, the two scores are not equally well evidenced: Re has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
