It's strange, because even though it's the exact same sculpt, the hatted head looks MUCH better and more accurate to me than the hatless head.
It's the same with Han. Instead of 100% of the sculpt having to be accurate, it knocks it down to 80% as they don't need to show as much of Ford or Hamil as the head gear covers the sides, forehead, hair. I'm just not buying the hair on either, but thankfully I was all about the hatted ones on both to begin with.
