The aem standalone does tons.

Antiag. 2 step. Launch control. It does traction control off of wheelspeed or rpm vs speed sensor. It will do traction control and boost control on a gear by gear basis.

When you get into high power you need more resolution, as the ecu averages the gaps between the data points, the bigger the gap between points the more chance there is for something to go wrong. Also with some applications you need the higher resolution just to tune.

Abs shouldn't have anything to do with the PCM. It has it's own control unit. I don't use abs on anything, crossfire included. Learning how to threshold brake teaches you better car control plus you can brake harder and later without having to worry about the abs freaking out on you.
