Not so at all when mixing and doing real time processing. All internal mixing/processing is done in the 32 bit floating point realm anyway (1500 dB headroom).
But… When doing a lot of OFFLINE processing (mathimatically altering the source file), it is an advantage with 32 bit fp and 24 bit vs 16 bit.
If you just mix perfectly good source files without a lot of offline processing, 24/44.1 is more than good enough.
