Why people look past CosmosDB
Nothing on the record flags a reason to move. CosmosDB has a free tier, and starts at Free against a category median of $25/month. People still switch over fit and workflow, and those are not things a catalogue entry can measure, which is what the comparisons below are for.

What you would be giving up
CosmosDB is most often brought in for running a globally distributed multi model database on azure, serving low latency reads and writes from multiple azure regions, storing document, key value and graph data behind a managed service. Anything replacing it has to cover the ones you actually depend on, and a cheaper tool that misses one of them is not cheaper.
Two things this page cannot settle. It compares on price, model, tier count and rating, because those are the fields the category listing carries, feature-level differences need both full records, which is what the head-to-head pages load. And the ratings are third-party aggregates imported with each entry rather than reviews written here, so a 0.2 difference between two tools is noise rather than a finding.
If CosmosDB is broadly right and the question is cost, the CosmosDB pricing breakdown covers every tier and what each one adds. If you want the whole field rather than a shortlist, the Databases category lists everything the directory holds, and best databases tools ranks them.
CosmosDB runs on web, azure. Platform coverage is not carried on the category listing for the alternatives, so it is one more thing to check on each head-to-head page rather than here.
