Not the OP, but I switched to Nightly a week ago and unlike stable I would recommend it to anyone. Not just to people who don't want to use anything Google. It's fast and doesn't hog memory. A far better experience than before.
Over the course of the next two weeks, they'll be merging some major UI overhauls, as well as remove swaths of legacy code, so things might be a bit rockier for some time and I wouldn't necessarily install it on my gramma's PC right in this moment, but other than that, yeah, it is pretty crazy how big the difference is, with Nightly being just three months ahead.
