I think the quality is very close although it is very difficult to compare accurately unless the two different players have exactly the same input file.

Immervision had the nice little navigation bar at the bottom. Immervision is more complex to setup.

A major factor is which stitcher you use and what file format it puts out.

Immervision images are encoded so they are more difficult to steal if thats an issue.

I’ve haven’t decided yet which I’m going to use for my tours.

I’m leaning towards Immervision just because of the nav bar at the bottom.. it may be easier for users to find their way back from fullscreen to the tour page.
