I think my biggest problem with inkscape is the tearing of the screen when I move the canvas around and it redraws. something about it makes the entire thing seem unstable to me. I dislike Illustrator but I feel like it could handle a big file better than inkscape, if inkscape can't even draw the screen fast enough. How will it handle the memory of a three-hundred thousand node vector image. Somebody tell me what the heck is that tearing happening and why after 20 versions isn't it improving?

As long as I work on Windows, there is Xara thankfully. It's got quirks but has been good to me and my workflow. On Mac now thankfully is Affinity Designer. Not quite fully fleshed out but still excellent to have. Inkscape is a great utility program for me that has a lot of low level tweak settings and it's great it constantly gets better.
