Having used a number of testing centers in the US across my training; they are not all alike. They are not vastly different either. If you have a few that are reasonably closed to you (don't wake up two hours early etc), then pick one that is quieter, easier to park, smaller, has close by food etc, may have local wifi from a neighboring shop so that you can have your laptop etc setup in your car (if thats still kosher, things may have changed) so that on breaks you can review things if you wish. Pick ones that have comfortable seats, carpet etc. You can tour the centers you are considering to assess these things. Make sure there are a few bathrooms instead of just one etc.
These are all minor things but if you have the option of a few local centers than you should definitely choose what suits you the best. It has been worth it to me…you make the call
