I'd agree with Gimp - it's UI makes several departures from other similar software.

But Inkscape's UI seems pretty intuitive?

Inkscape certainly has some idiosyncracies in its UI, but yeah, for the most part it's very reasonable and mostly adheres to common UI/UX conventions. Not sure how much it deviates from, say, Illustrator, as I haven't used the latter.
