Best Daydream VR Download Option?

[davidI]

I just got a Daydream VR with my new (discounted) Pixel XL.

It looks like a lot of content can be downloaded in Cardboard / Gear VR / Vive Oculus.

Which option should I choose for the Daydream VR? What's the difference between the download types?

In case anyone has this question in the future, after lots of experimentation it seems the Vive / Oculus downloads look best on Daydream VR, though I often have to manually select the 3D / 180 settings as Daydream doeesn't seem to pick them up.
