It's completely replaced my TrackIR 5, since it averts the need to wear headphones and dig out the tracking bracket every time I want to use it, and the accuracy feels about the same.
I found head tracking pretty much becomes second-nature after a while - to the point at which it feels weird to play first-person sims without it. Not quite as fancy as VR, but much more comfortable and much more practical.
