What is the best Facebook Client for iPad/iPhone?

Ever since upgrading to IOS 7, I'm not fond of my iDevices. Multitasking is awful! If I minimize Facebook to look at a web browser, when I go back to Facebook, it refreshes and starts me over again from the top. If I walk away from Facebook to go to the bathroom and come back to it, it refreshes and starts me over again from the top. If I go back more than 5 hrs of updates, it crashes! This is so %@&$ annoying since I use Facebook, not just for socializing, but as a source of news.

What is the best alternative app for Facebook? I'm looking for something that does not constantly refresh, has a bookmark feature and won't crash. Something that I can, at least, go back 12 hrs or more with. Android has a good app called Atrium but I need something for iOS.

Both I have an iPad and a iPhone I get FB on both and it works good
