Inkscape is good enough to replace Illustrator for everything I make, once I fixed the defaults

Even amid all the new design tool drops, Inkscape is still the open-source go-to for vector work. Plenty of Illustrator users who give it a try don't last a full afternoon, though, and that's because Inkscape isn't exactly a mirror of Illustrator, and also because the defaults probably won't get you far. Measurements read slightly off, then a resized shape drags its outline along with it, and the muscle memory shortcuts map to other stuff entirely. But you can easily skate past the friction of using Inkscape out of the box by changing the defaults. Everyone's workflow is going to require different tweaks, but these are the settings I'd pay attention to first when getting started.
