I am sorry I have not followed the discussions recently. I had happily settled on org-cite but I find that much has changed again. 

In particular, John Kitchin has given up the work on org-ref-cite and switched back to org-ref. There is a new org-ref version 3.0 which is not compatible with org-cite.

This obviously creates many problems including that two people using different citation systems cannot share org files.

What is the general view of the community about this? Is there a comprehensive discussion of pros and cons of each?

What is everyone doing? I was an org-ref user for long before I switched to org-cite. I can now shift to citar but since I am an ivy user, the switch is not trivial. Also, I like many helper functions that John has created, and would have to miss those if I do not use org-ref/org-ref-cite.

This seems messy.
