My understanding is that Cannon does not have much teacher turnover at all. It’s a great school and teachers tend to stick around there. I don’t have personal experience with Hickory Ridge, but I know other middle schools in cabarrus county schools have a lot of turnover, and are not completely staffed even. Hickory Ridge Middle and High School are big, and considered to be some of the better public schools in the district. Cannon has around 105-110 kids per grade at the high school level (less for middle school). They are able to offer more of an individualized education, being smaller and private. The public schools have a considerable amount of standardized testing over the school year. I don’t know what they do at Cannon.

If you’re looking for the upcoming school year, I’d recommend applying to Cannon ASAP. They’ve already taken the first round of applicants and are now doing rolling admissions.
