I compiled some height values obtained with Google Earth which I'd like to submit as corrections eventually. The main issue is that the level of agreement with the published values varies wildly: while a few are (almost) exact matches, some differ on the order of a few meters, and others (especially for older buildings) by even larger amounts.

Since there seems to be some consensus here in using GE as an acceptable source for heights, I ask at which point a published value can be deprecated in favor of ones obtained with GE (such as a cutoff)?

A consideration that might apply is that the 3D area I was working with isn't of quite good quality, and with areas like the ground level close to buildings having small irregularities generated it becomes hard to get heights accurate down to the meter.
