The graphical accuracy of the footprints does not affect the operation of the program. Each footprint is completely transparent to the layout application. As a general rule, it is worth considering that simplified footprints provide greater speed and response in layout management and accurate footprints allow user to have a more precise layout. Make an evaluation based on your business needs, taking into account the average complexity of your layout drawings. If needed, run a benchmark using a set of test footprints.
