Manual phone posting vs Facebook Creator Studio?

I feel like there should be a downside to your engagement when using Hootsuite or other 3rd party apps although I could be wrong, but then again Facebook has its own official tool for scheduling content...

Why?

All it is doing is automating posting, same as Hootsuite.

I have previously used later, and it worked fine, apart from posting stories, although currently exploring other options like Jarvee and searching for what else is out there.

I don't think there is much difference between the two. the important thing is to be in constant sharing with certain time intervals.
