Android != Maemo

Android is way more polished, smoother if you like, while Maemo behaves/is more like the typical desktop Linux OS. This makes it a hell of a great OS, but on a resource-limited device, it can get sluggish. This is where BFS jumps in.

BFS is designed with general Linux 'desktop' workloads in mind. It doesn't scale well with workstations/servers which have many cores. It is less complex and has less overhead than CFS. BFS doesn't focus on throughput, but rather on a more responsive desktop.

That's the reason I've been using it. User experience is really hard to measure, while static benchmarks generally don't represent the typical desktop Linux user's workload. Therefore, it is hard to prove the benefits of using BFS. I suggest you to try it out and judge for yourself.
