"so what your saying is the mapping in rb is a far greater
resolution than bb. "

In my experience yes, it's much more accurate in the Tempo Map for the ACW resolution.
Same is true in the MIDI resolution (which is huge, but a lot of people don't even think about it).

Being able to Edit/Generate down to 1/3480 of a single click compared to 1/120 is huge. That usually gets you down to a pretty small number of mS (and thus smaller 'sample' chunks in the audio edit area).

That same MIDI Resolution controls the From-Thru possibilities in both Audio Edit and Regenerate.

But back on topic, the ACW is more accurate in RB due to the Tempo Map accuracy in my opinion.
You can keep a more accurate tempo map and still generate to it.
