Hello! Welcome to our forum!
For the scale issues, please see these already existing topics:
Regarding the FAA sectionals - the new update has not introduced anything new in this aspect. There should be zero difference in the performance between the two!
Here is the old panel if you want to make a comparison yourself:

Please keep in mind that there have been a small sim update and a new beta release, so the simulator has also changed slightly and I cannot verify if this has affected the panel in any way.
Kind Regards,
Malte
