I switched from TIR to Tobii about 1.5 years ago, and it works really well for me. SU5 added much more native support for the Tobii, so Opentrack is no longer needed. Also, with Chaseplane, you can easily enable a function for your Tobii to freeze when you pause it so it stays looking at whatever switch or control you were looking at. Overall, the Tobii is much more refined now than it was even a year ago. It is so nice to not have anything attached to your head, and it now requires very little fiddling to get setup nicely. These are of course my experiences only.

The SU5 native support is somewhat better but it still doesn't implement all the Opentrack functions. You can't add curves, asymmetry or dead zones to axes. You also don't get the full 'Camera Boost' setup, although I don't find Camera Boost very natural. And you can't turn off the 'return to centre' behaviour when you toggle head tracking off, which is where we came in!

As per my comments above, you can IF you have Chaseplane. But, I know not everyone has CP or wants it, so that is what it is. Also, yes, Opentrack does have some extra functions that are not included natively. However, in my experience, Opentrack did not always work, and I was constantly having to fiddle with it. Now, maybe that was user error, but I did lots of research when using Opentrack and I just could not get it to work well all the time. Someone else's experience might be better than mine. What I like about the SU5 native support and also Chaseplane is that it was all easy to setup and works well. Curves are not yet available natively, but they did add limits so that when you lean your head it does not pop outside the aircraft and such. Also, when looking over your shoulder, it now behaves properly. All without Opentrack.

Have you considered Beam Eye Tracker? It does allow freezing of the current view. And a very reasonable price. You can try for free and currently has 20% off.

Interesting but I'm wondering how it compares with LookPilot and their tech support. I don't expect much given their pricing but still curious about community involvement in both.... Thanks.

Unfortunately I do not know anything about LookPilot, but Beam has a decent Discord server with fast responses from the dev team from my experience.

I'd go with the Beam:
