How we compare credentials
We don't score a credential solely on popularity.
The right credential depends on your actual entry point.
A learning program can be a better first investment for someone with no technical background, while an exam-based certification may be more useful for someone who already has foundational knowledge and needs a recognizable credential.
That's why our recommendations identify the user scenario first instead of declaring one universal winner.
