While I like how LR corrects lens distortion of my Fujifilm X10 automatically I do not like that it leaves me with no control whatsoever over the process. Compared to out-of-camera JPGs the LR corrections are more correct (no horizontal compression), but also cut away more information from the borders.
So without any control over the strength of the lens correction or at least a way to switch it off there always is information lost!
Here is a comparison of different lens corrections of the various raw converters vs. ooc jpg. As you can see by the uncorrected Capture One example there is more (distorted) information available than LR is willing to show.
