Co-op VR crossplay recommendations

Hi all what are your suggestions for oculus and vive user playing together co-op.

Main questions stems from Arizona sunshine vs Dead effect 2 since I don't know a lot of other similar games.

I also dont know what has crossplay (do we both need to get via steam or can I get via home and he get via steam and still play?)

• I assume we'd both need the steam version but unsure
