I used to have TrackIR and thought it was absolute pants. A very unnatural sensation when using it.
I've got a Vive Pro and after using that can think of nothing more immersion breaking than going back to TrackIR or something similar. The way it works is just so unnatural to how we experience the real world. I understand why people use it but for me it just doesn't result in a good experience.With the right settings it works well. That and a good webcam. Getting used to the moving screen can take a bit of time. It's easier to adapt if you've used VR I find.
