Route from Paducah, KY to Gettysburg, PA

The second week of June we are planning on going to Gettysburg and then Lancaster PA. We will be leaving from Paducah, KY and are trying to decide between going through KY to Morgantown WV then Hagerstown MD and then to Gettysburg (several choices from Hagerstown to Gettysburg). Or up through Ohio, Cincinnati, Columbus, then Wheeling WV and I-70 to the PA turnpike and across and down to Gettysburg. We have been to this area once before in a car. I think there would be more mountains through WV, but not sure about the later part of the Ohio route. My previous trip on the PA turnpike was expensive and the worst interstate condition I have ever experienced. Would like the opinion of someone that might have been the WV MD route or the Wheeling to Gettysburg route. Thanks for your responses
