That's been at least my experience. But I haven't used Photoshop in years now and got pretty much used to GIMP by now, for the once in a while that I use it.
And now I don't really have the annoyances anymore. I actually know pretty well how to do most basic stuff, and some handy keyboard shortcuts. And now GIMP doesn't feel that clunky anymore.
I have tried to use GIMP on dozens of occasions, and it always surprises me in the worst ways, or bounces me off to search the web for a howto. Simple things like: I want to select a rectangle, move/resize the selection, then crop the image to that selection. Or I want to arrange two images side-by-side for comparison, crop to the smaller one, to export a side-by-side. Pretty much every attempt at doing something other than colour curve adjustment has resulted in a faceplant. Eventually I gave up switched to Krita.
Overall, it works similarly to MacPaint from '84 and even has the same CUA keybindings.
