I use rmfakecloud even though i'm grandfathered in to the cloud. It's great.

I locked the fw on my remarkable 2 to 2.x and used ddvk hacks and it's just worked for years. I don't need any new features.

I've been considering downgrading tbh. The new stuff is mostly good, but the infinite-page conflicts a lot with other gestures (I really wish I could disable it) and it's overall noticeably slower nowadays.
