Online Learning Platforms

My school is starting to push the use of Google Classroom because we often use the G Suite Apps. Personally, I loved Google Classroom when I used it this past year. I found it really easy to use, but there are always good and bad things about every platform. The one thing I don't love about Google Classroom is that there is no grade book. There are some teachers in our building who really prefer Edmodo and would rather not switch to Google Classroom, but there is concern about trying to make the students learn and use multiple platforms for different classes/teachers. What online learning platforms do you use and like? Tell me your favorite below.
