It has a nice banner image that makes the app look sleek, plus you can set privacy setting from within the app, for instance you can set what group of your Facebook friends can see your activities.
The one problem I have with this app is that you cannot manage your Facebook page from the app, this has to be fixed (hope Microsoft/Facebook are reading this). But everything else is very good.
You cannot go wrong with this one.
With Facebook App...
You can post status updates, receive Live Tile updates, check your news feed, review upcoming events,
check in to places, manage your inbox, upload photos, publish notes, accept friend requests, pin Places
and Messages as Tiles, and look at your friends’ photos, walls and info. And don’t forget about Facebook Chat – it’s built into the Messaging app on your Windows Phone. New for version 2.3: view Groups, visit Pages, set post privacy, view who Liked your posts, filter your
Feed, view optional banner photos (turn on in settings), and enjoy the updated navigation. New for version 2.4: restored Events link on main panorama.
