Where each one falls short

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

Argo CD

Licensed under Apache License 2.0 per the project's GitHub repository (argoproj/argo-cd LICENSE); as open source software it has no paid tier or vendor price to compare
The quick start installation requires the --server-side and --force-conflicts flags due to CRD size limitations, per argo-cd.readthedocs.io, a constraint the documentation states explicitly

KnowBe4

Published prices assume a three year term, so the quoted per seat rate depends on a long commitment
Pricing is banded by seat count, and the lowest band of 25 to 50 seats pays the highest rate
Accounts above 1,000 seats have no published price and require a custom quote
Third party integrations, Compliance Plus and PhishER Plus are all separately priced per seat add ons
The Foundation tier carries 200 training modules against more than 1,000 on Advanced, so content volume is the main gate
