I tried it but like most note taking apps like this, I feel like that drawing with vectors just doesn't feel that great: The stroke changes a bit after being jotted down, the curves sometimes end up jagged, the erase experience sometimes leaves to be desired. And selection/lasso are either missing or underpar.

Mischief was the last app with this kind of features that felt right to me. I don't know if it's the use of ADF (Adaptively Sampled Distance Fields[1], think SDF but defined as quadtrees[2]) or what. Honestly if it wasn't for the lack of a lasso tool (which I was always hoping it would come until it died) I would still just use that.
