I've been using it for about 2 or 3 years - basically since it's first release. And I actually think the latest app is the best they've done yet. Which isn't really saying much given the latest app still sucks badly.

But around 2 years ago, it was so bad I was running 3rd party Facebook clients on Android - some of which were littered with adverts.

When being subjected to numerous intrusive adverts is less annoying than using the ad-free official app - well, then you know the in house developers clearly need a lesson in mobile development.
