Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Arnica

CKAN

The package install path requires Ubuntu 20.04 or 22.04 64-bit specifically; other operating systems must use the source install
Only Solr 9 and Solr 8 are supported, and from CKAN 2.10 they are the only Solr versions supported at all
