Is it better for Nero CD/DVD Speed to have WNASPI32.DLL?

Nero CD/DVD Speed seems to work without the WNASPI32.DLL, so I assume that it’s using SPTI. But I notice that the CD/DVD Speed website says that “an ASPI manager is highly recommended”. Why is that? Will it give better results if you use the WNASPI32.DLL, or will SPTI work just as well?
