Where each one falls short

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

Kong

The Plus plan includes 1M API requests a month and charges $200 a month for each additional million
Plus is capped at 10M requests a month, so growth past that forces an Enterprise contract
Plus limits published APIs to 20 and includes one Developer Portal, with a second at $200 a month
SSO and audit logging are Enterprise only
Enterprise pricing is custom and billed annually

Rancher

Another platform to run and keep available, and an outage in it affects access to everything it manages
Meaningful overhead if you only operate one or two clusters
Version compatibility between Rancher and managed Kubernetes versions needs watching during upgrades
Support requires a SUSE subscription; the project itself is community-supported
