Inkscape is (speaking generally here, not just about performance) pretty good on Linux, tolerable on Windows, and awful on Mac. That's kind of a hole that a lot of cross-platform apps get stuck in, though-- especially GTK apps (which, historically, haven't supported the Mac well at all), but even QT (which at least tries to automatically adapt to macOS idioms) doesn't quite get it right. MacOS UI conventions are just too far away from Windows and Linux conventions to expect to be able to get them for free.
FWIW, at some point last year, I switched away from Illustrator to using Inkscape, for better native SVG support. On my wacom-enabled Coffee Lake Thinkpad, I've yet to find an app in either Windows or MacOS that's as responsive to pen input as Inkscape is under Linux.
It's just a shame that Gnome support for mobile Intel graphics sucks so badly.
