Agreed that scrolling is still janky, but the syncing of prefs (especially add-ons) is well worth it, imo.

Heck, even just the one add-on that lets you sleep your phone while a YouTube video continues playing is well worth using Firefox. Such a basic functionality isn't enough reason to get YouTube Red.

And then, you have add-ons like ublock origin that give you the Brave-like functionality without all this brouhaha.
