The short version

Each has a real cost: Census census was folded into Fivetran Activations, per the vendor: "Previously, this was called a sync in Census", and its own pricing page redirects to Fivetran pricing rather than showing Census plans; CouchDB append-only storage model may have performance implications for certain workloads with high update rates
They diverge on capability: Census covers Reverse ETL, CouchDB covers Multi-master Replication.

Where each one falls short

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

Census

Census was folded into Fivetran Activations, per the vendor: "Previously, this was called a sync in Census", and its own pricing page redirects to Fivetran pricing rather than showing Census plans
Free Fivetran Activations tier caps at 3,500 monthly active rows

CouchDB

Append-only storage model may have performance implications for certain workloads with high update rates
Requires network synchronisation for cluster data consistency; can introduce latency in multi-master scenarios
No explicit support for complex joins; MapReduce queries may be inefficient compared to relational databases
