I like crown molding, but it needs to be in the right kind of house. It doesn’t work so well for modern/mid century modern houses. Crown is great for my mom’s 1877 farmhouse. I have a 1980’s ranch, so anything goes. I’ve done crown molding in parts of my house, as well as hers. It’s not that hard if you have some skills. For corners, I either bought the specially-made pieces for the corners or made my own from pieces of 4x4” post that I cut at a bevel on the two sides that show.
