@ivan.popelyshev thanks for the warm welcome and the detailed answer. I will make sure to dive in a bit deeper on some of the topics you highlighted.
To give a bit more context, I was asking the question with the mindset of experimenting on a new project and wanting to make the best bet as to which method was most likely to be the correct one in the long run so that as I progress and build things, the chances of me having to switch over to the other method are as low as possible. I don't know if that makes sense but I'm still pretty new to all of this.
For the moment, though, what I get from 👆 is that both ways I have described of moving things around are equally good from a general purpose standpoint. Basically, if we were to take all the likely use cases of PIXI.Graphics, both methods would, on average, perform about the same and I therefore do not have any reasons of favoring one method over the other when experimenting and my use case has not become quite clear yet. Am I understanding your point correctly?
