[D] Between Coursera and Google Cloud Skill boost, what's best to prepare for the ML Engineer Professional exam?

Hi everyone, I want to complete the Google's ML engineer certification exam in a few months from now and I found 2 usefull resources to practice:

1- Coursera: Preparing for Google Cloud Certification: Machine Learning Engineer

2- Google Cloud Skill Boost: Machine learning engineer path

I know a lot of people do the Coursera course, but have you guys heard about the second one?

Thank you
