I use safari on my Mac and Ipad/Iphone but i do find it more clunky to use on the Ipad than i do the Mac. I must admit i'm a bit behind with OS software upgrades on the iPad
Just as a test i just upgraded the OS on the Ipad2, its made no difference to the operation of Facebook or UKgser, face book buttons still needs to be double operated to work at times.
I use a browser called Atomic. It can also block ads.
Main problem is it, as with any other 3rd party browser, does not integrate with the rest of ios. So if you click on a link in the mail app, for example, it will open safari.
