Valve had an early lead with the Index and has plenty of titles in its store that were designed for the Index. Then Oculus came along with the Quest and many of the titles were ported over there.

Even though Quest ports exist, the versions on Steam may have controls that don't work with Quest controllers over Steam Link.
