Inkscape is free, open-source, and not cloud based — and is less user friendly, has a much higher learning curve. GIMP, which is comparable to Photoshop, works okay with Inkscape, but is not comparable to the ways Adobe’s products work together.
Personally, I enjoy using Inkscape because I value the freedom it provides. Including knowing that if I create an digital asset with it and backup the build used it create it (OS, Inkscape, etc) - very likely I’ll be able to edit the file as it was when I created it; same is not likely true for Adobe products, especially over long time periods.
Highly recommend if you’re using either that you also understand the SVG file format and stick to it as much as possible.
If you have any additional more specific questions, happy to try and answer them. Love vector based graphics.
Beyond that, as I mentioned, GIMP is not comparable to Photoshop. If you’re going to be using Photoshop with vector based digital assets, not aware of any reasonable justification not to use Adobe’s vector application over Inkscape.
Beyond that, Adobe’s asset management and workflow management applications don’t compare to anything that’s available to anything that’s available within Inkscape.
If you’re aware of any counter claims, would welcome any more specific thoughts you have on topic.
* support for CMYK work, as well as spot colors, and the whole dark art of color profiles - last I checked Inkscape was RGB-only and there are things involved in professional printing that you simply cannot do without CMYK and spot support
* global color swatches (change the swatch, everything you drew with it changes to match)
Also having 20y of Illustrator files on my hard drive that I regularly pull elements and appearance stacks out of for reuse is a compelling argument for me to stick with AI.
