If you just want a program for making vectors, then Inkscape will probably fill that role. If you wanted to do graphic design work, then it would probably make sense to bite the bullet and get the Coreldraw .
Corel Draw does lots of things Inkscape does not do, but as far as vector illustration goes, all vector illustration software does most of the same things: shapes, paths, node editing, text, clones, symbols, etc. . The shortcuts will be different, and some tools are unique to each program, or will require fewer/or more steps.
I use inkscape to save and export as SVG or DXF file . Making a really good SVG in Inkscape can take a while on sufficiently complex images. I have a XP-Pen Deco 01 drawing pad to use with Inkscape for node editing and drawing new art.
