Looking for a camparison between AppSheet and Microsoft 365 Power Apps

Hi. I am a co founder in a start up in Medellin Colombia. The purpose is to teach Social Emotional Learning to kids using music and art. We have an administrator who is familiar with Power Apps and is not familiar with Google workspace. She wants us to change our platform to Microsoft 365 to use Power Apps. Right now we are using Google Workspace but we have not gone live with clients yet and will not do so until Jan. I have a bias against Microsoft and really do not want to change if we do not have to. So my question is about the differences between the two. Has anyone used both of them and can tell me anything about this? I am wading into the weed rapidly and am having trouble comparing the two, particularly on prices. Thanks in advance for anything you can tell me.
