Yes, in some words:
RTAI is much faster, but relies on the kernel you have, so it is much more complicated to be included in software parts. It is mostly needed only for very high speed applications PREEMPT-RT is a a little bit slower than RTAI, but can be implemented in software much easier, just imagine it is a modul. That is very simple explained, there are more differences. For a normal CNC opperation both should work fine. But if you use i.e. software stepgenerator over a LPT, than take the RTAI.
