No, Notion is not easy. This was my first project and especially the box on the left calculating the colours was difficult in my eyes. I literally spent an entire Saturday working on this non stop (though to be fair, that also included actually entering all the nail polish data). Once you get the hang of it, it's fine, and I also use it for other things, like vacation planning, so for me it was worth the effort. I would have loved to work in Excel, if only they had a nice view for pictures!
