I have a 9.25" EdgeHD and while it doesn't have any significant problems with chromatic aberration at the f/10 focus it certainly does have mirror flop. With its built-in mirror locks the problem isn't too bad (but movement in the primary mirror can still occur). However, it can have notable issues with mirror flop if you don't tighten down the locks.
In terms of CA, well, the EdgeHD series is pretty well corrected although its off-axis spot diagrams do show differences between red, green, and blue (at its native f/10). Furthermore, Celestron's EdgeHD 0.7X reducer almost certainly introduces some amount of CA, although not nearly as much as you'd see with a typical ED refractor.
All that said, I think the EdgeHD series performs very well. I do have some reservations about the smaller, 8-inch model (it's kind of an EdgeHD "lite"), but that scope is relatively inexpensive in comparison to the larger models.
