Where each one falls short

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

Valkey

Younger project, so its track record is short even though the codebase is not
Divergence from Redis grows over time, so compatibility is strongest near the fork point and weakens as both evolve
Ecosystem tooling and documentation still frequently assume Redis, leaving translation work

Marqo

Pricing not publicly available, enterprise sales-only model
Requires custom implementation and integration work
Limited to ecommerce use cases compared to general search
Model training requires sufficient customer behavior data
