rsvg has had a bunch of annoying bugs and in general seems to be further behind in terms of sorted compliance and feature support. When I was creating SVGs for Wikimedia Commons I had to work around a number of rendering bugs. And I didn't even use Inkscape, I wrote SVG by hand. In contrast, the lead developer of Inkscape is active both in code and on the SVG specification mailing list, oftentimes implementing new features ahead of time to see how well they fit into SVG and where the spec might still need to be changed. In practice, when valuing spec compliance and feature support, Batik and Inkscape are the only sensible options. This has nothing to do with quirk compatibility.
