How many use Github Actions and Why?

I am really curious to know if devs and QA engineers like to create functional and executable code blocks in a web app versus writing it as a python script?

For example, if I was a developer using GCP-APJ and AWS-US-east for storing images, then I will have to create a script internally that hooks into both these cloud vendor APIs to perform similar functional things like uploading new content, deleting images, etc.

Question for the group here:
a) As a developer would you use a system like Github Actions to do this? if yes, why?
b) if you don't intend to use Github Actions, then what other use-cases would you use Github actions for?
