Physical reset button vs. factory defaulting thru camera web interface

[msquared]

Is there any difference of results in these two methods? Is one better than the other, or will the end result of the camera state be the same via either method?
If a user was having an issue with a camera would the button reset solve issues that a software factory default would not?

In my experience, there did seem to be a difference. The physical reset made the camera stable following a firmware upgrade. A real shame that this seemed to be needed.
