I've only used Scratch a little, but I must admit I found the interface fairly complex and arbitrary, somewhat reminiscent of the complexity and arbitrariness of normal programming syntaxes. As simple a thing as putting one new instruction in between two existing instructions can be a multi-stepped process, creating temporary intermediate structures that work better. But admittedly I didn't power through (or rather, power through with the kid) to the other side, so it might have ultimately been simpler than textual syntax, even if it's not actually easy. Hopscotch, an iOS app basically like Scratch (https://www.gethopscotch.com/ https://www.gethopscotch.com/), seemed significantly better in this respect. The quality of your draggable UI matters quite a bit in a graphical language! Given how few of these languages exist, maybe it's not the model but just a lack of rigor applied to the UI challenges of the model.
