CZ-75!!!
As far as the AR-24 being more ergonomic... what? CZ does offer different frame shapes, not all CZ-75's are the same. I do think the "best" frame shape is the CZ-75B SA and the SP-01 (I think the grip shape is the same), ever so slightly better than the original CZ-75 IMO. They are all so good that I really can't see it being much of an issue, for myself anyway.
