Illustrator is, but I don't think Inkscape is. I haven't been able to find any real information about Inkscape adoption rates, but I participate in several vector forums and Inkscape only ever comes up in terms of amateur illustration.
I would love to be wrong about this.
Figma and Adobe Xd are pretty popular, as is Affinity Designer. Microsoft Visio is popular in certain contexts, and InVision Studio is also popular.
I own Adobe Creative Suite but use Inkscape for illustrations embedded in web pages because the svg source is cleaner* and diff-able, meaning, the illustrations can be checked into GIT and convey sensible (minimal diff) history of changes. Haven’t checked in a few years to see if Illustrator cleaned up yet.
// Similar to the typical problem with HTML generators, they’d write nasty code, so most were write only rather than write/read. To be fair, I haven’t checked Illustrator output in half a decade, so it could be fine now.
/// Definitely trying your tool, thank you for sharing!
Inkscape and gimp are the only tools I use for image editing. I'm a developer working in B2B manufacturing so the aesthetics of my work don't really matter.
Just an anecdatum, at UIUC's fab lab we taught Inkscape to all ages, it was really useful to import an image, trace bitmap to an SVG, and send the SVG to vinyl cutters, laser cutters, 3d printers... I think we were not the only fablab to do this, and hopefully it is popular in other educational circles.
