The simple answer is: the one made by the camera company.
For example, a Canon TC is guaranteed to work with Canon cases and Canon lenses.
But, once you move to third-party goals or third-party goals (Kenko, Sigma, etc.), the warranty disappears. The reason it's about getting into the electronics and the technology built into the lens, the TC and the camera – but the end result is that you should never expect that a goal or a CT works with a box if the manufacturer so wishes. (For example, if Kenko claims that his TC is working with 80D or 70D and 70D and 70-200 and 70-200L lenses, he is missing the 80D or Sigma lenses from his approved list … so you do not have any proof that his TC will work with this device or lens).
TLDR; there is no TC list approved for autofocus. There is only the TC, and its camera body and lens combinations are approved. If you leave these stories, you are in unknown territory. Things can still work, but do not be surprised if they do not work.
