Calling anyone familiar with mapping the state of Pennsylvania in the US!

My map seems to be a bit distorted: the southern border curves slightly and the western border is slanted. I've seen maps where the southern and western borders are straighter so that the state more closely resembles a rectangle. I know that distortion is a necessary evil, but I was wondering if anyone had any thoughts as to why this may be happening and if there were any fixes? Or, is this an accurate potrayal of the state and I shouldn't worry?

For context, I'm working in ArcMap 10.8.2. This map is using the USA Contiguous Albers Equal Area Conic coordinate system (and is rotated so that it's not diagonal), but similar distortions are happening with the NAD 1927 StatePlan Pennsylvania North and South FIPS coordinate systems. The county shapefile came from a national 2024 TIGER/Line file downloaded from the US Census website.
