Can you post examples that aren't at full effect?
Most of what I've been playing with is fine with the post crop effect.

I'll try to illustrate the problem in this way:
First two screenshots attached are a neutral gray wall shot as a reference in order to find the settings for pre- and post-crop vignettes that would give the same effect. As you can see, I was unable to get an exact match, even disregarding color, though it's close.

Screenshots 3-4 (house and mountain scene in DNG format) show the images after the pre- and post-crop vignettes are applied (synced from first two images). Notice the effect is drastically different in both cases.

Screenshots 5-6 show the same image after I attempted to equalize the histogram using Exposure and Brightness. Notice that in the post-crop vignetted image, I was unable to equalize the histogram without trashing all information in the sky. Therefore, this image is significantly darker than the pre-crop version. Also, the colors and contrast are weak in the post-crop version.

Screenshots 7-9 show a different image (this time a TIFF) with the same results. I was able to equalize the histogram this time, but colors and contrast still suffer.

Like I said before, I've tried fiddling with contrast, curves, saturation, etc. to make the post-crop images look similar to the pre-crop versions without luck. Now, I'm no expert, but it's obvious to me that the post-crop vignette does not function in the same way as the pre-crop version. This may have been the plan all along, but in my opinion, it's far inferior to the original.
I'm at a loss to understand why Adobe would add the post-crop feature at all instead of simply altering the original "lens correction" vignette tool to work on cropped images. Like the last version of PS, LR just got bigger but not much better, meaning that many photographers, myself included, must still use both overpriced apps to do one thing.
