Tannehill Ironworks Historical State Park

Would any one be willing to compare Tannehill with Brierfield Ironworks Historical State Park, which I understand is similar but smaller. Tannehill 256 sites vs Brierfield 25. We're looking at it from a camping point of view, nice spaced sites with trees, clean restrooms, relatively level sites. And assuming a smaller park might mean less crowded. But again a smaller park might not have all the sights and historic structures as the larger.

Thanks
