It only seems to be some Americans pronounce it nitch, so maybe regional there, though I couldn't guess where or which is most common. Here in the UK essentially always neesh.
It is from French after all.
Edit: American audiobooks on the other hand seem to go 100% with nitch for some unexplainable reason.
