I don't think the accuracy will be the same. Some have the wrong crown guard(162 for sure, perhaps 188 and 196 depending on series number). Some probably have wrong millesimation on the case back (xxx/500 when it should be 1500, etc.) and I also suspect different dials will be more accurate than others. I know that on the 162 it is still unclear whether the sub dials are exactly the right color. So pick carefully. But yes the overall quality should be about the same except that QC pics have shown some pieces to have better aligned crown guards than others, etc. The quick pusher changes the date. It requires a tool of some form to push the little button. A pencil actually suffices.
So you should decide on your favorite one and research it.
