As far as I would say the difference is about "realtime"...
emulation runs in real time, so it is limited by the CPU of your computer.
simulation is normally "event driven", which allows you to take some
time for complex computation but makes it difficult to use unmodified
And running a special implementation of "protocol X" in a simulator
might give you unexpected results that you cannot verify with the real
