If you have a preexisting community somewhere (a newsletter for example) and you want to interact with them, YouTube Live is a great tool to do that. In my experience, a Live is great to make announcement, discuss topic or even make interviews if you integrate it with Zoom. I guess it's not as useful if you haven't build a community yet, since people are not going to show up on your live if they don't know that you exist.
It provides a lot of tools, but in order to be a 10 it should be a little bit more "visually friendly". Also it contains so many options all at once that it can be overwhelming. Other than that, it's a great software for your business/personal project.
YouTube Live Is more cost effective it is more widely seen easily available and better while I have used Facebook Live, Linkedin Live, instagram live YouTube Live is more easier. to use, but combined with a multi streaming platform the net effect is excellent and you can actually stream to all the platforms together at the same time
