byuu wrote a good article about this, unfortunately it's no longer available, but basically it should be self-evident that there's nothing inherently more accurate about hardware emulation.
If you've actually decapped the original chips and duplicated them exactly in an FPGA, that's pretty cool. But otherwise it's just another approximation. The lower power requirements are nice, of course.
