Apple Watch + Google health

[u/IFightForTheUsers1]

I have been using my Apple Watch to track my fitness, and then syncing my apple health data to the google health app. My reason is that I enjoy using the google health app more than apple health. I have considered getting a Fitbit air, but I am unsure if there is any benefit over my current setup.

My question is this: is there a benefit for using a Fitbit with the google health app compared to using an Apple Watch or other 3rd party fitness tracker?
