I just bought an apex and haven' t shot it yet. I do know that functionally it is pretty good. The primer can be installed and extracted easily by hand. One of the problems I' ve encountered with 209 primers is that they don' t seat easily and can fail to discharge on the first try. They other problem is that they are hard to remove which greatly complicates a follow-up shot. They apex doesn' t have these problems. Should be very easy to service also.
