I keep switching it back on after having it off for a while. I want some autocorrect. I often like the type ahead suggestions. I just really hate the "update behind" mechanic.

It's real frustrating that Apple has decided to put just about everything under only a single Settings switch and won't break it out into individual things.

It's also frustrating that for about half an iOS version Apple seemed to have caught on that the update behind was catching people off guard and implemented an extra, more obvious change animation. The whole word flashed in a bright blue or yellow when it changed and had a visible undo button. That was useful. But then the button didn't survive the next point release and the animation kept getting subtler again until it disappeared.
