There’s a little more to it than that. 24p and 24pA can both be edited at 23.98 or 60i because that’s how they initially exist on the tape. 24pA can be automatically converted to 23.98 by FCP’s Automatic Advanced Pulldown removal whereas 24p standard must be reverse telecined manually via CinemaTools. So- yes if your desire is to edit at 23.98, 24pA makes it much easier than 24p standard but either can be cut at 24p or 60i.
