Indeed, that is primarily where it excels. Your layered source files are SVG and you can export to SVG (and you can import in SVG obviously). The bitmap selection/exporting is also excellent as such you can have these massive vector canvases (with any number of bitmaps and vector shapes/graphics mixed in) and quickly export any slice or selection you make without having to resize the canvas or copy/paste somewhere - and it will remember the export path when you click on the object or layer again later (aside from a bug with symlinks on Linux); ideal for iterative work/exporting revisions to clients or colleagues.
Yeah it's great for SVGs. I still use illustrator because the type tools are a lot easier to work with for constant use,I already have a CC subscription grandfathered in at a cheap rate, and some things in it I'm just plain-old used to... But I could deal with Inkscape if I decided to dump Adobe. Gimp not so much. I'd definitely be buying affinity's photo editor or something for raster work.
