> Blender is a cross-platform, open-source design tool, and it manages to have a tight, professional looking UI Well let's remember that there was HEAVY criticism of Blender's UI up until the 2.5/2.6 releases, with some people even criticizing it now that 2.8 is released. There was an extreme amount of work done since 2.5 to clean up the UI. It also has a lot more functionality than Inkscape, and so I think there is incentive as more people start using it to make sure that all those functions are filed away neatly and accessible without cluttering the interface too much. Also, just going on users subscribed to their respective subreddits, Inkscape has around 6000 and Blender 151,000. So the size of the user base might have a direct impact. Personally I don't find the Inkscape UI to be all that bad, although I agree it could do with some tightening up. I still prefer to use Adobe Illustrator if I have it to hand, but Inkscape will always work in a pinch. Being able to use it to create SVG that can be directly imported into Blender as curves is something I've used it a lot for, for that kind of task they complement each other very well.
