Where each one falls short

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

The Growth plan requires a minimum $4K/year commitment to unlock discounted rates.
Enterprise features and custom SLAs require a direct sales conversation rather than self-serve signup.

Self-hosted Enterprise requires a minimum of 5 seats and an annual contract.
Additional API traffic beyond the included quota is billed per million requests.
