It's usually better to Live bounce anyway for the best quality.
Unless there's an issue with a particular plug-in, there is no difference in "quality" between fast and real-time bounce. Per Cakewalk's CTO, they use the same code, just not limited by the real-time clock (nor by the real-time buffer size if you set a value for BounceBufSizeMsec other than 0 as bitflipper mentioned).
If there's a problem with a plug-in, it will generally manifest in an obvious and extremely unpleasant way, not a subtle difference in quality.
You can test for yourself that fast-bounce and real-time exports will null to silence when re-imported and played back with one inverted (being sure to freeze all synths and FX first to lock in any randomness that might be built in to their processing algorithms).
Because it's not limited by the burden of clocking buffers in real-time, fast-bounce is actually
less error-prone than real-time.
