Parent is correct, high CRI[1] is what you want to look for. I'm embarrassed to reveal how much time and money I've spent down this rabbit hole and ultimately went back to halogen.
As you research, you'll discovered that there is in fact more to the single CRI value. It is actually an average measurement of a range of different colors.[2] R9 in particular is the one that is hardest for LEDs to reproduce. Some manufactures goose their CRI value by getting high scores for the other values even though their R9 or R13 (skin tone) is poor.
