What magnification level should I look for in a lighted makeup mirror?

Most reviewers across r/MakeupAddiction and beauty retailer reviews recommend 5x to 10x for general makeup application, with 10x being the sweet spot for brows and eyeliner. 15x-30x mirrors exist (the MIYADIVA and B Beauty Planet candidates here) but several verified-purchase reviewers note that level is more useful for tweezing and skincare than for makeup, and one Costco.com reviewer specifically flagged 10x as already 'much too strong' for some users.
