Q-tips were very clearly designed to clean ears. They just have to cover their ass now, and tell people it's not safe. (I do not personally have very gooey ear wax and don't use them much at all)
As someone with wax issues in the ears, no, q-tips suck at cleaning ears. You'll end up pushing the wax into your eardrum and causing the impacted wax that you were trying to avoid in the first place. That's why I use those tiny screwdrivers. /shrug
I frequently need to clean my ears due to wax issues and I have used q-tips to do so for my entire life. I have only ever been told that my ears are immaculate at anual exams so this definitely depends on the person.
I think it depends a lot on what type of wax you have, which can vary depending on your ethnic/racial/generic background. For some people it's like wax, for others it's more like caked dirt - potentially q-tips are better for the former.
