+10^10^10 betaflight is better
I tend to stay on cleanflight. Features get merged in from betaflight eventually and I don't have to worry about broken builds.
From what I hear they don't always merge the changes, hence why lots of people are using Betaflight.
I held back from using betaflight for ages. I finally took the plunge and I haven't looked back. My quad now feels like it is on rails, and it was my first build and it's far from photo worthy.
Install betaflight, you'll love it, take my word for it. And if you don't just go and put Cleandlight back on (this won't happen!)
